Gamepad Input Latency Tier Lists (Wired & Wireless) - Hardware Tested

Transparency Disclosure: Most of the controllers featured here were purchased with my own money, while roughly a third were provided by various brands for review. I have no active sponsorships or commercial interests tied to any brand in this post. The rankings are based purely on raw hardware measurements collected over the past year. Additionally, the images were generated using a custom tier builder I created for my site, Gamepadla, which is completely free for anyone to use.

Hey everyone. I'm sharing two latency tier lists for gamepads - covering both wired and wireless connections - based on data gathered using the Prometheus 82 hardware test bench for measuring input lag.

To give a better idea of actual in-game responsiveness, the tier list uses a weighted grading system called LatScore. This score accounts for button latency, stick latency, and signal stability (jitter).

Here is how the calculation works:

  1. Base Latency: A weighted average prioritizing stick responsiveness over buttons. Base = (0.4 * Button) + (0.6 * Stick)
  2. Dynamic Jitter Penalty: Unstable connections get penalized. The higher the jitter relative to the base latency, the harsher the penalty multiplier (capped at 1.5x). LatScore = Base + Jitter * [1 + min(Jitter / Base, 1.5)]

Grades are assigned automatically based on the final LatScore thresholds:

  • Up to 5 ms: S (A+)
  • Up to 10 ms: A
  • Up to 18 ms: B
  • Up to 25 ms: C
  • Up to 35 ms: D
  • Up to 45 ms: E
  • Above 45 ms: F

Basically, this means a gamepad with highly stable latency gets a better grade than a controller with lower average latency but frequent, large spikes. Stability matters more here than raw average numbers.

One quick note on reading the charts: The order of the gamepads within the same tier does not matter. They are not sorted by exact sub-latency inside their specific letter grades.

The attached images show the tier distributions. I've included the names of the controllers directly under their icons so you can easily find specific models. If you want the exact millisecond readings (base latency, jitter, etc.) for any specific gamepad, just ask in the comments and I'll provide the details.

Just a quick note on the data: This list strictly includes verified entries to prevent any unvetted or random results. While most of these gamepads were tested internally by Gamepadla, about 40% of the data was contributed by trusted hardware reviewers and vetted community members utilizing their own Prometheus 82 test benches.

Steam Controller Analog Stick Linearity Analysis: Comparison of Connection Modes

For a long time, the original Steam Controller remained excluded from detailed instrumental linearity tests due to its specific data transfer format, which is not recognized by standard software bypassing the Steam client. Following the implementation of direct low-level coordinate reading into the Python-based Line testing utility, it became possible to thoroughly evaluate its analog stick behavior across three modes: via the proprietary wireless receiver (Dongle), a USB cable, and Bluetooth.

Testing Methodology

The test was conducted in a series of consecutive passes using a linear actuator on the Prometheus 82 test bench to eliminate accidental errors. The scenario involves moving the analog stick from the geometric center to the outer edge as smoothly as possible. For comparison, movements identical in duration - exactly 3 seconds each - were selected. This made it possible to evaluate pure data stream density, linearity, resolution, and the level of micro-deviations (tremor).

Testing the linearity of the Steam Controller using a linear accuracy tester

The overall linearity pattern of the stick itself proved stable across all modes (97.1% - 97.5%). The graph features a barely noticeable acceleration of readings in the central zone ("hump"), yet the trajectory remains predictable. The main differences lie in the polling frequency and packet structure.

Summary Table of Results (Movement Duration - 3 s):

Connection Mode Total Points Points After Filter Tremor Level Polling Rate
Proprietary Dongle (Dongle mode) 792 570 28.0% ~260 Hz
USB Cable 731 531 27.4% ~240 Hz
Bluetooth 398 369 7.3% ~134 Hz

Connection Modes Analysis

Steam Controller linearity test via the receiver

1. Proprietary Receiver (Dongle) Demonstrated the highest data density at 570 real stick positions and maximum resolution. The tremor level is 28.0%, which is the baseline index for this hardware, and the micro-noise is noticeable only under extreme graph magnification.

2. USB Cable Connection Within the identical timeframe, the gamepad transmits less information - 531 positions, while maintaining the same tremor level (27.4%). The cable provides equivalent accuracy.

Steam Controller linearity test via the cable

3. Bluetooth Connection The polling frequency here is the lowest (around 134 Hz), resulting in the lowest number of points after filtering - 369. The graph appears artificially clean (only 7.3% tremor), because the low polling rate of the Bluetooth bus simply fails to capture the minor hardware sensor fluctuations that slip between the sparse data packets.

Steam Controller linearity test via the bluetooth

Technical Confirmation: The Real Value of Higher Frequency

A series of additional retests clearly confirmed a hardware pattern: the original Valve wireless receiver operates at a higher polling rate than the cable (peaks up to 270 Hz versus 250 Hz over USB).

The filtering log analysis completely refutes the theory of an artificial ("padded") polling rate. If the extra packets from the receiver were just digital duplicated noise or empty data, they would be entirely discarded by the utility's algorithms as garbage. In that case, the number of points after filtering (After filter) would be identical on both the receiver and the cable, and the tremor percentage on the wireless interface would spike dramatically.

Report on the Line test console application

The test math proves the exact opposite: alongside the total packet count, the amount of useful data on the receiver increased proportionally. After filtering out the noise, the receiver preserved 570 clean points, compared to just 531 on the cable. Because of this, it guarantees higher granularity, registering more useful stick micro-movements during gameplay.

Conclusion

Instrumental testing confirmed excellent analog stick accuracy across all connection modes. The main distinction is data density: the proprietary wireless receiver consistently registers more useful stick positions than both USB and Bluetooth, providing slightly higher movement granularity without additional noise.

Whether this offers a tangible gaming advantage will ultimately be determined by latency testing, but the receiver has at least one measurable benefit over the cable: it captures more intermediate stick positions and micro-movements during the same physical movement.

Polling2 update: Direct HID support for Steam Controller

I have just released version 2.0.2.6 of Polling 2, which now adds native support for the Steam Controller.

What this measures
This update calculates the true polling rate based on the actual coordinate updates from the analog sticks. It measures when the hardware physical position changes, rather than just the speed at which the port sends data.

How to get accurate results
Because this method relies on detecting changes in stick coordinates, you need to rotate the stick quickly and consistently during the test. This ensures the software captures the true frequency of the hardware's data output.

Download the new version here and let me know what polling rates you are seeing on your controllers: https://gamepadla.com/soft.pdl

Steam Controller magnetic pack causes stick drift (Testing & Proof)

While testing my Steam Controller, I noticed it suddenly started drifting. I didn't get why at first, but then I realized I had left the magnetic pack attached to the bottom. It turns out the magnetic field really messes with the stick sensors and ruins the circle error. It is better to keep the pack off while you are playing.

This controller is actually one of my favorites in my entire collection right now, so I have been digging deep into how it works. I have already finished testing the input latency and will share those results soon.

Steam Controller 2.0 Raw Polling Rate Tests: Going Beyond Steam Input Limitations

Hello r/SteamController!

I recently tested my Steam Controller 2.0 using Stick Tracer Web. The main highlight of this test is getting direct access to the gamepad, bypassing the standard Steam Input emulation layer.

As many of you know, Steam Input creates a bottleneck for the polling rate, and in the case of the Steam Controller, it limits the polling rate for the client application to around ~120 Hz. Because of this virtual buffer, we simply do not see the hardware's true potential for this specific controller.

My test bypasses this intermediate stage using WebHID technology. Thanks to WebHID, the software gets direct low-level access to the device and polls the controller directly via the Steam protocol, showing the raw, unthrottled polling rate of the hardware itself. The results for the three connection modes are quite interesting.

Polling Rate Results:

1. Puck Mode (Native Wireless Receiver): 272 Hz The highest polling rate achieved, with the native dongle outperforming even the wired connection!

Steam Controller 2.0 polling rate (AVG) via Receiver

2. Cable Mode (Wired): 249 Hz A stable and expected result for a wired connection.

Steam Controller 2.0 polling rate (AVG) via Cable

3. Bluetooth Mode: 133 Hz The lowest score, with pure BT expectedly lagging behind.

Steam Controller 2.0 polling rate (AVG) via Bluetooth

Stick Parameters Overview:

Since I have previously done a detailed breakdown of stick parameters in this community, I will keep this part very brief:

  • Circle Error: Within 8.1% - 9.3% for both sticks across all modes. When analyzing this metric, the most critical factor is not the raw error percentage itself, but the overall geometric symmetry of the shape. Any structural excess (axial values extending past the 100% bounding box) is naturally clipped at the engine level by most modern games. Therefore, the main objective is achieving a balanced, uniform shape to prevent unpredictable sensitivity jumps when pinning the stick in different directions. The Stick Tracer Web charts reveal excellent symmetry here: the right stick exhibits an almost perfect circular boundary, while the left stick has a minimal rightward shift, which is non-critical and likely down to specific hardware unit variances.
  • Drift Error: Ranges from 3.3% to 4.3%. You might notice these numbers can slightly vary from test to test or are higher than in my previous report. This is a cumulative result of a few factors. First, the controller has been actively used, so the internal stick springs have naturally loosened up a bit over time. Second, the WebHID version utilizes a much stricter and more meticulous algorithm. It targets the most critical potential drift and micro-movements, making the web tool far more demanding and less forgiving. This range could definitely be significantly reduced if the device had a calibration function, but for sticks without artificial software auto-centering, this is still an acceptable working range.
  • Resolution: A stable 11.5 bits in all three tests. In simple terms, this means around 1448 registration points when moving the stick from the center to the edge. The precision is excellent.

The Main Mystery: What About Input Lag?

Logically, a higher polling rate should have a positive impact on input latency. The previous latency tests for this gamepad that you might have seen showed the following metrics: around 6 ms over cable, about 9 ms via the native puck, and almost 10 ms over Bluetooth. Since those measurements were routed through Steam Input, the 120 Hz cap and its virtual wrapper clearly distort the true hardware picture.

Announcement: Right now, work is underway on refactoring the testing methodology to measure input lag directly from the Steam Controller, completely bypassing Steam Input.

It will be fascinating to see the raw hardware latency numbers without any artificial limitations, and to compare how the connection modes hold up against each other under raw conditions without caps. Stay tuned, I will share the latency results as soon as the updates are ready!

P.S. Although it may seem that the polling rate is better on the receiver, in reality it still does not exceed 250 Hz simply because of the less stable jitter and the fact that the algorithm, which calculates the average value, creates a greater spread in the data. I have now reworked the metric to use the median, with the option to select a test algorithm in the future.

Steam Controller 2.0 Analog Stick Benchmarks & Full Technical Breakdown

Hi everyone! I’ve been professionally testing gamepads for over two years now, focusing heavily on input latency and stick behavior. I’m new to this sub, so I wanted to share some of my recent data without any fluff.

While I usually focus a lot on latency, today I want to look exclusively at the analog sticks of the Steam Controller 2.0, as they are crucial for a precise and consistent gaming experience. I recently ran them through my testing routine, and the results are incredibly promising.

Steam Controller 2.0 Analog Stick Benchmarks

1. Inner Dead Zone: NONE

This is the area around the center where small movements are ignored. Just like most modern high-end gamepads, the Steam Controller 2.0 allows you to completely remove it. The stick responds immediately to even the slightest movement, which is excellent for micro-control and custom response curves. This makes it a great choice for precision-heavy games.

2. Outer Dead Zone: <0.3 mm

This metric limits the useful travel distance of the stick near the edge, causing "lost" range. In the Steam Controller 2.0, it is almost non-existent (measuring 0.3 mm on both the left and right sticks). Both sticks show the exact same behavior, suggesting consistent edge behavior between movement and camera inputs, which is another great win.

3. Stick Asymmetry (Partial Travel): 14.0% (Left) / 3.6% (Right)

This is one of the most critical tests I’ve developed, utilizing physical travel limiters that restrict the stick's deflection to roughly 70-80% from the center. This reveals the true performance in the ranges most critical for gameplay. Testing at 100% often hides asymmetries because the firmware clamps the maximum value into an artificially smoothed shape.

If you look at the stick charts, this partial deflection test is represented by the inner blue area. The actual shape of this blue area shows you exactly how symmetrical the stick's physical travel is across all directions.

In our case, the shape itself is almost a perfect circle on both sides, which is great. However, the alignment differs:

  • Left Stick (14.0%): The picture here is a bit mixed. While the shape itself is round, the entire inner blue circle is programmatically shifted slightly to the right of the axis center. This shift is why it scored a higher 14% asymmetry. It's definitely a bad indicator, but it hasn’t crossed into the critical red zone yet.
  • Right Stick (3.6%): This is the best thing I have ever seen in the history of this testing. The blue area is perfectly centered and beautifully round. 3.6% is phenomenally low, and without exaggeration, the best result among all gamepads tested so far. High-end controllers typically strive to stay below 10%. With this level of symmetry, you can fully rely on your raw aim and build perfect muscle memory. I’ll share my thoughts on this below.

4. Circle Error: 8.2% (Left) / 9.1% (Right)

Nothing critical here. This gamepad lacks heavy programmatic outer-edge smoothing (which forces a perfect 0% circle error). However, my previous research and testing have proven that this does not negatively impact gameplay or aim precision.

The reality is that most modern game engines handle this automatically. They read the X/Y coordinates as a vector and simply clamp the maximum input length to 1.0 inside their own code. Since the stick's travel remains perfectly linear and predictable all the way to the edge, the game engine just rounds it out without any loss of control. Valve chose not to force artificial smoothing filters here, avoiding the micro-input lag or axis magnetism that often plagues controllers trying to chase a marketed 0% error.

5. Stick Bitness (True Resolution): 11.4 Bits

Everything is top-tier here. Higher bitness allows the controller to register more distinct positions, ensuring smoother cursor translation without "stepping" or pixel-skipping during slow, precise aiming. My True Bitness metric is derived from actual physical movement, not just declared digital specs. 11.4 bits is massive - it corresponds to a Step Resolution of 0.00073 and allows the stick to register roughly 1,365 unique position points from the center to the edge of the axis. There is no practical reason to make it higher; this completely covers the needs of any player.

6. Stick Centering: 2.9% (Left) / 1.7% (Right)

This measures how accurately the stick returns to absolute zero (neutral) to prevent stick drift. For the Steam Controller 2.0, it is not critical (under 3%), which is quite good. It is worth noting that this test uses a rigorous methodology implementing small-angle deflection and release, which simulates normal micro-adjustments during gameplay rather than standard maximum-deflection snaps. This is much better than standard Xbox controllers, where centering error can easily reach 6-10%.

7. Axis Magnet: NO

This is a form of processing where the stick artificially "snaps" or clings to the X or Y axes, distorting diagonal inputs. There is no axis magnetism here, meaning your true movement path is fully preserved. This is the preferred behavior for consistent aiming.

8. Polling Rate: 120.7 Hz (Via Steam Input)

The testing suite reported ~120 Hz because it runs through Steam Input, which limits the refresh rate due to its buffer protocol. However, natively, the gamepad operates at 250 Hz, which can be seen using alternative testing software that communicates directly via WebHID. Keep in mind that Stick Tracer is not a specialized tool for precise polling-rate measurement, so some margin of error is expected.

9. Center Skip: NO

Stick skipping is entirely absent here. This means the stick begins moving gradually and smoothly right from the neutral position without sudden coordinate jumps, ensuring excellent fine control.

Conclusion

As far as I'm concerned, the sticks on the Steam Controller 2.0 are almost perfect. The only thing they are missing is a robust hardware/firmware recalibration tool. Proper calibration could likely fix the 14% asymmetry found on the left stick.

As of right now, to the best of my knowledge, no such option exists. I really hope Valve adds a recalibration feature in future updates - if they do, these sticks could easily claim the undisputed #1 spot on the quality charts.

What are your thoughts on these metrics? Let me know if you want to discuss the methodology!

Launch of a web based controller tester with full Steam Controller support (Stick Tracer Web)

Hey everyone,

Testing gamepads straight in the browser is super convenient, but finding a reliable web tool that fully supports the Steam Controller is surprisingly hard. To solve this, a browser based version of the Stick Tracer app was put together. The goal was simply to create a clean, accessible interface for quick controller diagnostics without needing to install any extra software. It can be found here: https://gamepadla.com/test/

Currently, this seems to be the only web tool right now that actually supports testing the Steam Controller properly.

Here is what can be tested right in the browser:

  • Live Polling Rate (Hz): Real time measurement.
  • Stick Drift and Circularity Error: It calculates automatically, just rotate the sticks and leave them alone.
  • Advanced Stick Visuals: Exact X/Y coordinates can be shown. Raw Mode can also be turned on - this disables interpolation so it doesn't draw fake extra points between actual physical movements.
  • Trail Modes: Set it to "Constant" to draw and keep all stick movements on screen, or "Fade" to make the trail slowly disappear as the sticks move.
  • Vibration Test: Controller rumble can be triggered right from the page.
  • Triggers and Buttons: Pull depth graphs and an input state monitor.
  • Gyroscope: 3 axis motion data.
  • Mode detection: It automatically sees what protocol is being used (like Steam mode).

If something is confusing, just click the "i" info button in the top right corner - it contains a breakdown of how everything works.

The tool is still in Beta and is actively being tweaked. Feedback is highly appreciated. If there are any suggestions or bugs found, just drop them in the comments!

I built a free, zero-setup Web Gamepad Tester (Live Polling Rate, Stick Tracing, Drift %)

Hey r/controllers. I'm new to this community, but I wanted to share a project I've been working on. I develop testing tools over at Gamepadla, and I recently decided to build a web-based gamepad tester that runs directly in your browser with zero downloads or setup required.

It is essentially a lightweight web version of my desktop application, Stick Tracer. You just plug in your controller and it instantly starts reading data.

Here is what it currently measures:

  • Live Polling Rate: Real-time monitoring of your controller's polling rate in Hz.
  • Visual Stick Tracing: See the exact input paths of your thumbsticks.
  • Automatic Drift Detection: Calculates base drift from the dead-center position as a percentage.
  • Circularity Error: Maps the outer boundary and calculates the error margin.
  • Input Mode Detection: Automatically identifies if your controller is using XInput, DInput, Sony, or Switch modes.

I literally just pushed this script live today, so it is in a very early beta phase. Because it is so new, I haven't had the chance to test it across a wide variety of hardware configurations yet.

If you have a few minutes to plug in your own controllers, your feedback would be incredibly helpful to me:

  1. Does the site correctly identify your specific connection mode?
  2. Are there any UI glitches, or does the tracing feel unsmooth on your setup?

You can try it out here: gamepadla.com/test

Please drop any bug reports, UI feedback, or feature suggestions in the comments. I plan to actively polish this tool based on what you guys find.

GameSir G7 Pro 8K Aimlabs Edition: Latency Test, Real Stick Bitness, and Non-Obvious Nuances

Disclosure: This specific controller was purchased completely independently using crowd-funded subscriber donations via Ko-fi, meaning GameSir had zero involvement in sourcing this device and has no editorial input, influence, or early access to this post. Please note that as an independent developer, I license my custom Prometheus 82 hardware testing bench used in this review to various brands for internal QA, and GameSir currently holds one of these commercial licenses; however, they do not sponsor, fund, or dictate my benchmarking methodology, and no financial incentives, agreements, or affiliate links exist between us regarding these independent test results.

Hi everyone! Today we are looking at the GameSir G7 Pro 8K Aimlabs Edition.

Instead of a standard review, we will look at the measurement results using my custom hardware test bench, Prometheus 82, and the Stick Tracer utility. There are many interesting technical details here that usually go unnoticed.

GameSir G7 Pro 8K Aimlabs Edition on the P82 test bench

TL;DR / Key Test Results

Parameter Result
Stick Latency (Cable, Xinput 8K) 0.69 ms — stable sub-millisecond result
Stick Latency (Cable, Sony 4K) 0.63 ms — record result, despite lower polling rate
Wireless Latency (Bluetooth, Sony 800 Hz) 3.45 ms (stick) / 3.58 ms (buttons)
Real Stick Bitness 15-bit (left) / 14-bit (right) instead of the claimed 12-bit
Tremor 92% of informational spam in 8000 Hz mode
Stick Asymmetry ~10% (left) and 11% (right) — almost in the "green zone"
LatScore Wired A+ / Wireless A+ — maximum possible score

1. Honest 8000 Hz over Cable: What the Software Shows

Claims about "1 millisecond latency thanks to 8000 Hz" are often purely marketing. However, GameSir has actually implemented this polling rate. I tested it with separate Polling software (which measures polling rate strictly and does not affect input latency).

GameSir G7 Pro 8K Aimlabs Edition Polling Rate Chart

The gamepad delivers an honest 8000 Hz. The median in the test is 7936 Hz (average — 7863 Hz), but in peaks, it reaches a clean 8000 Hz. The jitter of the polling itself is tiny — only 0.05 ms, and the maximum polling rate latency is 0.76 ms.

These numbers are so small that GameSir literally forced me to redesign the graph rendering on the Gamepadla website. Previously, sub-millisecond results simply merged into a single point — the system's interface just wasn't designed for such speed. In this way, the gamepad went beyond what my own website expected. This is probably the best illustration of how serious this leap is.

2. Stick Input Lag and the Sony Mode Anomaly

GameSir G7 Pro 8K Aimlabs Edition Latency Chart

Cable (Xinput, 8000 Hz)

The stick latency is 0.69 ms. Even considering measurement error factors, this is a real result under one millisecond. On the graph, the bars are clearly saturated without any gradient, indicating virtually zero latency spread. This is one of the best results I've ever seen.

Measurement Accuracy: Cross-Checking

My colleague vCuda tested this gamepad over a cable on Windows 10 (firmware 2.1.0) and got 0.68 ms. On Windows 11 with the same firmware, I got 0.69 ms. The difference between two independent tests on different machines and different OS versions is just 0.01 ms. This simultaneously confirms the surgical accuracy of Prometheus 82 and the extreme stability of the gamepad's hardware itself. If the gamepad's performance fluctuated, the results would have diverged. They did not.

The Sony Mode Anomaly

Over a cable in Sony mode, the gamepad runs at a maximum of 4000 Hz (median 3906 Hz, sometimes the frequency drops to 2700 Hz). However, the stick latency here is lower than in Xinput at 8000 Hz — just 0.63 ms! This confirms the fact that polling rate affects latency, but not as straightforwardly as commonly believed. I previously wrote a large separate article about this: How polling rate affects controller latency. As an example, a recent test of the Astro C40 TR Wireless showed only 3 ms over a cable at a 250 Hz polling rate.

3. Dongle vs. Bluetooth: Speed and Stability

The GameSir G7 Pro 8K Aimlabs Edition received a Wired A+ / Wireless A+ score in my LatScore system — this is the maximum possible score on both channels simultaneously. This combination is extremely rare and puts this gamepad into a separate category of "uncompromising" devices in terms of speed.

However, there are nuances in wireless modes:

Bluetooth (Sony Mode, 800 Hz): Latency sits at 3.58 ms for buttons and 3.45 ms for sticks. For context, GuliKit recently announced their Hyperlink 2 tech with a 2–3 ms wireless response as a revolutionary breakthrough, yet GameSir has quietly matched those indicators right here, right now, without any loud marketing. The only catch is typical for Bluetooth: due to signal interference or the quality of your specific PC adapter, you might encounter rare latency spikes up to 17.9 ms.

Bundled Dongle (2.4 GHz): The average latency is slightly higher (~3.5–3.9 ms), but the stability is significantly better — the stick spread ranges from 3.5 to a maximum of 6.4 ms, without any sharp spikes.

Conclusion: Bluetooth is completely usable, but for total stability without potential spikes, choose the bundled receiver.

4. Stick Analytics in Stick Tracer

GameSir G7 Pro 8K Aimlabs Edition - Stick Tracer Results (Cable/Xinput)

Dead Zones: The inner dead zone is completely absent. The outer dead zone is only 0.3 mm on both axes. This allows you to use the entire physical range of stick movement as efficiently as possible.

Asymmetry and Centering: Asymmetry is 10.4% for the left stick and 11.2% for the right stick. These are good results, almost in the "green zone." Centering (drift) sits at 1.5% and 2.7%. In the absence of artificial center-holding algorithms, this is completely normal for pure spring mechanics.

Behavior: Axis snapping (Axis Magnet) and missing coordinates (Center Skip) are absent.

Bitness Test and the Tremor Phenomenon

My algorithm for testing real resolution (bitness) is designed for a very slow stick movement from the center to the edge. It registers only increasing data, ignoring jitter and tremor — meaning it counts specifically the "useful" movement of your finger.

Although we select the 12-bit mode in the official software, we actually get 15-bit on the left stick and 14-bit on the right stick. This is a near-record figure; for comparison, the maximum software resolution is 16-bit. The 12-bit mode in the software simply removes any limitations, while the 10-bit mode limits the range more strictly.

The flip side of high resolution is tremor. In 8000 Hz / 12-bit mode, we have 92% tremor. During a slow movement from the center to the edge, the gamepad registers 46,283 data points, of which the useful finger movement is only 3,719. The rest is repetitions and microscopic coordinate spam.

The red dots on the coordinate system indicate tremors

Experiments with settings showed that lowering the bitness does not reduce tremor (at 1000 Hz / 10-bit it is 69%). However, lowering the polling rate has a strong effect: at 1000 Hz / 12-bit, tremor drops to 65%.

This coordinate spam does not affect gameplay at all — your crosshair will not shake. When switching to 1000 Hz, the latency increases by literally 1 millisecond, which is not critical. Therefore, 1000 Hz is a perfectly reasonable choice. But if every fraction of a millisecond matters to you, leave it at 8000 Hz.

5. Configuration and Linearity Nuances

RAW Mode: An Unexpected Reversal

In some previous GameSir models, Raw mode always provided better latency. In the G7 Pro 8K, the developers changed something in the algorithms, and now the situation is reversed: enabling Raw increases stick latency. We don't know the exact internal reasons behind this change, but the result is clear: using this mode now simply makes no sense. The default boundary circularity is already perfect (Circle Error is only 0.1%).

Linearity Curve: A Change of Philosophy

In the Aimlabs Edition, GameSir shifted their long-standing approach. Previously, they promoted a natural curve with a slight dip downward — it corresponds to the actual physics of a joystick potentiometer, which is fixed at one point and moves like a pendulum (meaning perfectly linear physical movement does not exist). Competitors with perfectly flat lines use artificial correction.

Linearity Curve G7 Pro vs Aimlabs

Now, GameSir's default curve is also "perfectly flat," just like most competitors. Whether this is good or bad is up to you. On the plus side, in the app, you can customize it to any taste and even bring back the natural look. Furthermore, thanks to this flat-curve approach, the custom curve you draw in the software will match your real-world linearity results even better, as you no longer need to compensate for the hardware's natural slope.

6. Ergonomics and Subjective Impressions

When the technical tests are over, it's time to evaluate the gamepad purely as a user. The internal hardware is excellent, but in daily use, small details emerge that no software can show. The following is strictly my personal opinion, and you don't necessarily have to agree with it.

Button Print Quality: If you look closely, you can see a dot structure consisting of micro-dots of white and blue colors. It doesn't look as premium as solid paint or double-shot plastic, where symbols are molded in a different color. The gamepad itself feels nearly premium, and that's precisely why this nuance stands out.

Plastic D-pad: The D-pad is ordinary plastic. Coming from an Xbox Elite controller, I subjectively miss metallic elements. If GameSir ever sells a metal D-pad separately, I will buy it immediately.

Stick Durability: On the other hand, the rubber on the bundled blue sticks was a pleasant surprise. During latency tests on Prometheus 82, a solenoid hits the stick sharply and forcefully — many gamepads start rubbing against the housing "into dust" within the very first cycles. GameSir's stick showed zero wear after this torture. However, due to the semi-transparent texture of the blue plastic, it will be interesting to see if it yellows over time from finger contact. Time will tell. The extra sticks in the box are black, even though blue ones are pictured on the packaging.

Final Verdict

The GameSir G7 Pro 8K Aimlabs Edition is a massive technological leap. The manufacturer managed to break the sub-millisecond barrier, delivering a real stick latency over cable of 0.63–0.69 ms, while also squeezing a very serious speed out of Bluetooth. The massive real stick resolution of 14–15 bits and near-zero dead zones make this device ultimate hardware for competitive gaming. A final score of Wired A+ / Wireless A+ is the maximum you can possibly get on Gamepadla.com.

Yes, for extreme speed, you "pay" with a colossal coordinate tremor in 8K mode (though it doesn't hurt your aim). The numbers speak for themselves — this is undoubtedly a highly capable and impressive controller. Only time will tell how durable it proves to be in the long run.

Did anyone else get the blue/teal sticks with their G7 Pro 8K Aimlabs?

Hey everyone! Just got my G7 Pro 8K AIMLabs Edition from Amazon US (ordered May 2nd) and noticed two things:
1 The Sticks: The pre-installed sticks match the teal accents perfectly, just like on the box. But the extra ones in the kit are completely black. Did anyone actually get the fully matching extra sticks as shown on the packaging, or is everyone's extra set black?
2 The Fit: Is it just me, or are these thumbstick caps insanely tight? Trying to pull them off feels so stiff that I'm honestly terrified of breaking the analog mechanism.
Anyone else facing this with the recent batch?

Astro C40 TR in 2026: Does this PS4 Legend still hold up? Latency &amp; Stick Analysis

Disclosure: This controller is part of my personal collection, purchased with my own funds. I acquire hardware independently to ensure complete objectivity and transparency in my testing. This review is driven solely by my personal enthusiasm and technical interest, without any involvement or sponsorship from the manufacturer.

Astro C40 TR

The Backstory

I finally managed to add this icon to my collection. Since you can't buy them new anymore, I hunted down a refurbished unit on eBay. Back in the PS4 era, this was widely considered the "G.O.A.T." pro controller, and I wanted to see if it still earns that title in 2026.

Latency: Surprisingly Fast

I ran a full battery of tests on PC, and the wired results are honestly impressive for its age.

Astro C40 Wired and Wireless latency (AVG)

Despite a modest 250 Hz polling rate, the optimization is top-tier:

  • Wired (Cable): Consistently measured around 3.3ms for buttons and 3.1ms for sticks. This is lightning fast even by modern standards.
  • Wireless (2.4GHz Dongle): The performance here is more "of its time." It averages around 14.9ms - 16ms. When you factor in the jitter (around 2.2ms), it’s closer to a C-grade performance. It’s not terrible for the era it came from, but it’s certainly not the "wow" factor you get when using the cable.

Stick Performance & Build

The sticks use traditional potentiometers, but the implementation is very high quality.

  • Calibration Magic: One of the coolest features is how this controller calibrates itself. You simply press a button, leave it untouched for about 20 seconds, and it handles everything automatically. It’s incredibly convenient and user-friendly.
  • Excellent Symmetry & Circularity: Despite being 8-bit (which was the standard at the time and offers roughly 127 steps from center), the sticks show good symmetry. The circularity test is nearly perfect; there is a very slight offset, but it's practically unnoticeable during gameplay.
  • Low Outer Dead Zone: The sticks have a very small outer dead zone (0.3 mm), which is a huge plus for maintaining a full range of motion without "hitting the wall" early.
  • The Centering Issue: On the downside, the Stick Centering (drift index) is around 6.7% and 5.2%. Even after multiple recalibrations, this remains a bit to high.

Final Thoughts

I’m really glad I finally got to test this beast.

The lack of a Type-C port isn't the only sign of age; the 8-bit resolution is quite low, and the sticks are dated potentiometers. While I haven't found any modern Hall Effect alternatives currently available (only modules with different tension seem to exist), the modular design at least makes replacements possible. However, even with these flaws, it remains arguably the best pro controller you can get for a PlayStation 4. It was an absolute "top-tier" beast at launch, and in 2026, it still feels incredibly premium and capable.

Hey everyone,
I wanted to share a repair log for my BEITONG Kunpeng 70. The stick base (the stem under the cap) cracked after just a few of my technical tests. I've tested dozens of controllers, but this is a first for me to see a stick fail this quickly. My testing involves very high stress levels, and the stock plastic just couldn't handle it. Superglue was useless here due to the mechanical load.

The Repair Process:

  1. Modeling: I designed a replacement from scratch in Fusion 360. This controller uses an internal contact mechanism, so the smoothness of the inner ring is critical. The flatter and more precise the inner surface of the printed part, the better the stick's movement and circularity will be.
  2. Printing: Printed on my Bambu Lab A1 Mini. I usually prefer a 0.2mm nozzle for this, but I only had a 0.4mm nozzle available at the moment. I decided not to wait and went ahead with it — the result works perfectly.
  3. Testing: I verified the repair using Stick Tracer. I checked for 100% deviation and symmetry; the results are almost identical to the original performance.

The model’s accuracy is nearly perfect.
I’ve uploaded the STL file so you can fix your Kunpeng 70 if you run into the same issue.

Recommended materials: PLA+ or PETG. Happy printing!

I bought the GameSir Tarantula Pro specifically for my collection. Symmetrical controllers are rare these days, and this one has a mechanical trick I didn’t even know about until I opened the box: the button layout physically swaps inside the housing. You can actually watch the gears turn through a small window. It’s pure, child-like joy — a rare "wow" moment in modern hardware.

However, once I hooked it up to the Prometheus 82 to run some tests, I discovered some interesting technical nuances regarding the stick modes.

The Technical Trade-off of "Enhanced" Mode

The Tarantula Pro features two stick modes: Raw and Enhanced. On paper, Enhanced mode looks great as it uses algorithms to correct stick geometry, bringing circularity error from ~7.8% down to nearly zero.

But my testing reveals a significant trade-off:

  1. Symmetry: In Raw mode, the stick actually describes a more symmetrical and uniform circle at ~70% tilt than it does in Enhanced mode.
  2. Latency Impact: There is a noticeable difference in response times depending on the mode. Here is the data from my measurements:
Connection Raw Mode Enhanced Mode Latency Increase
Wired 12.7 ms 27.6 ms +117%
Bluetooth 25.4 ms 36.4 ms +43%
Dongle 29.9 ms 42.8 ms +43%

As shown, Enhanced mode increases latency across every connection type, more than doubling it when playing wired. For most users, Raw mode offers a much more responsive experience while maintaining better symmetry at partial tilt.

How to Switch Modes

To toggle between Raw and Enhanced modes (the manual refers to this as the "Zero Dead Zone" setting), use the following shortcut:

  • Long press M + LS/RS for 2 seconds.
  • The setup is saved even after a restart.

How to Verify Your Mode

You can verify your active mode using any online gamepad tester or Stick Tracer. If your outer circularity shows a slight natural error (~7-8%) — you are in Raw mode. This is the recommended setting for the best performance.

Verdict

The mechanical gear system is brilliant and honestly one of the most unique features I've seen in years. However, if you want the most responsive experience, I highly recommend sticking to Raw mode. It provides a significant boost in speed (12.7ms wired) and better overall stick symmetry compared to the Enhanced setting.

The numbers are stable and reproducible. For those interested in the full breakdown, including button latency and jitter analysis, you can find the complete report here: https://gamepadla.com/gamesir-t3-pro.html
