one day, i boot up gd, then its just laggy.

i assume its just loading, so i wait.

and wait.

and wait.

still LAGGY!!!

so i restart, problem persists, and that happens 3 more times.

let me explain what happens, there’s three types of lag:

1. It stays at 60 fps, but stutters for 0.5-1 seconds at ~51 fps
2. Capped at 34, goes down to 30, and repeat, maybe 2 times a second
3. It just goes insane (fps just goes crazy like 31, then 2, then 60 for a few seconds, then 52, then 4, blah blah blah repeat)

since then ive tried literally everything:

1. Closing everything I can in the background
2. Updating my drivers (all were the latest versions)
3. Changing graphics settings (low, medium, high)
4. Removing every Geode mod (as in taking them out of the mods folder)
5. Setting GD CPU priority and affinity to High and All Processors
6. Playing around with every single setting in the Graphics portion of settings (eg. setting fps bypass to double my framerate (60), turning on and off VSync, Smooth Fix, and Borderless)
7. Using the 2 to 4 gb thingie
8. Setting everything that MUST run in the background to efficiency mode
9. Turning on the something something fullscreen optimization setting in GD’s compatibility settings
10. And as a last-ditch effort, using the sketchy apps that claim to “boost” your game’s performance.

+ it only lags on GD, but if I decide to run Minecraft, it’s completely and perfectly fine

And most annoying of all of this:

it just decides to run properly whenever it wants, as in stays at 60.

be it in the pause menu of windy landscape or in the advanced graphics menu

help

or do i go to an it guy

Hi guys, could really use some opinions on this because I’ve spent ages troubleshooting it and I’m starting to think my 5800X might actually be faulty.
My system is:
MSI MPG X570 Gaming Plus
Ryzen 7 5800X (upgrade)
Ryzen 7 1700 (old CPU that I’m using for comparison)
Hyper 212 Black cooler
16GB DDR4
Windows 10
BIOS E7C37AMS.AR4, build date 13/08/2026
Windows installed on a Fanxiang S500 Pro 256GB SSD
Basically, the PC was working with my old Ryzen 7 1700. I upgraded to a 5800X and started getting constant random blue screens/restarts.
The stop codes aren’t even always the same. I’ve seen things including:
KMODE_EXCEPTION_NOT_HANDLED
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
IRQL_NOT_LESS_OR_EQUAL
The crashes can happen extremely quickly, sometimes when the PC is basically doing nothing.
Here’s what I’ve tried so far:
BIOS: The motherboard is on E7C37AMS.AR4 from August 2026 and detects the 5800X correctly. BIOS itself seems completely stable. The 5800X sits around 38–39°C in BIOS, so it doesn’t appear to be overheating.
RAM: A-XMP is disabled and the RAM is running at 2400MHz. I’ve also tested using individual RAM sticks in A2 and the crashes still happened.
PBO: Found Precision Boost Overdrive under AMD Overclocking and disabled it for testing. Made no difference.
Windows: I originally wondered whether Windows/drivers were corrupted, but I booted directly from a Windows installation USB and the PC still blue-screened while sitting in Windows Setup. So it doesn’t seem to be my actual Windows installation.
I’ve also previously done a clean Windows 10 installation, so I’ve already spent quite a bit of time ruling Windows/boot issues out.
CPU cooler/mounting: I wondered whether I’d overtightened the Hyper 212 or seated the 5800X badly. I loosened the cooler previously and it made no difference.
Today I decided to do a proper CPU comparison.
I removed the 5800X and put my old Ryzen 7 1700 back in. Ironically, the 1700 had previously had some bent pins that I carefully straightened. I checked them, installed the CPU properly, fresh thermal paste, mounted the exact same Hyper 212 and booted it.
The 1700 booted straight into Windows.
I left it sitting at the lock screen and desktop and it was stable. Restarted into BIOS and it was still completely stable. CPU temperature was around 33–35°C.
I then removed the 1700 and reinstalled the 5800X extremely carefully.
I checked the 5800X pins and they all look straight. It dropped completely flat into the AM4 socket without force and I locked the lever normally. Cleaned both the CPU and cooler, applied fresh thermal paste and remounted the Hyper 212 evenly in a cross pattern. I deliberately didn’t crank the cooler down excessively.
Booted the PC and the 5800X actually made it all the way to the Windows lock screen.
I thought I’d finally fixed it.
Then after sitting there for a few minutes without me doing anything, it blue-screened again with:
KMODE_EXCEPTION_NOT_HANDLED
So at this point the comparison is basically:
Ryzen 7 1700 = stable
Ryzen 7 5800X = random BSODs
Same motherboard.
Same RAM.
Same GPU.
Same PSU.
Same SSD/Windows installation.
Same cooler.
Same everything apart from the CPU.
I’ve now gone back into BIOS with the 5800X and loaded Optimized Defaults as one final test. A-XMP is off, RAM is at 2400MHz, the motherboard detects the 5800X correctly and it’s around 39°C in BIOS.
Is there anything else BIOS/voltage/CPU-related that you guys would test before I call the 5800X faulty and return/RMA it?
The fact that the 1700 works in exactly the same machine but the 5800X even crashes from a Windows installation USB is what’s making me think the CPU itself is the problem.
Any ideas appreciated because this one has been driving me mad lol.

I switched to the Epic version and it helped but I still have absurd framerate drops in some GMs and arena ops and other random places. Arena ops gets so bad I guess because of having 6 guardians.

I'm on a laptop that should be able to handle it no problem. 5080 laptop, 32gb ram. The part that i SUSPECT could be an issue is the CPU: Intel(R) Core(TM) Ultra 9 285H (2.90 GHz)

I was troubleshooting with Claude and the issue as it describes is

"Your Core Ultra 9 285H is a weak gaming CPU for single-threaded, memory-latency-sensitive workloads, so in older/DRM-heavy titles like Destiny 2 and AC Odyssey — which funnel everything through one CPU thread — it becomes the bottleneck and your framerate drops while your RTX 5080 sits mostly idle."

Does this sound right? Is there some dumb setting that's going over my head? I can try to summarize all the troubleshooting I've tried later i just wanted to get this post up

Whenever I play games it happens at random times, sometimes it takes a long time someone's no time at all

I've tried:

Replacing PSU

Reseating GPU

Reseating ram

Upgrading GPU drivers

Replugging the wires that plug into the GPU

Updating windows

Edit: Tried stress testing cpu, cpu and memory, vram, GPU, GPU and vram All above 10 mins each and not a single crash, tried reinstalling both drivers and windows and still the issue persists
