Input lag issues with Gulikit Es Pro
Ever since I bought this controller, it has had input lag issues on my PC, but it wasn't persistent and was easily solved by resetting the controller or restarting the PC in more serious cases. However, now this problem is unbearable and very persistent.
It works perfectly for 1 minute, and after that time, it starts to lag.
The reason I didn't return the product is that I was never able to confirm whether the problem was specifically with the controller or with my computer.
I ran a performance test using the XInputTest software:
Maximum delay of 303.72 ms
64 serious outliers were detected in only 4000 samples
Average polling rate was 172.86 Hz
Jitter value of 0.39 ms
I don't know exactly what these numbers mean, but I know they are very bad
I'm using a Bluetooth adapter. All my Bluetooth-enabled devices work perfectly with it, except for my Gulikit ES Pro controller.
I use Windows 10 and my PC has a good configuration.
Solutions I've tried that didn't work:
- Move the Wi-Fi router further away to avoid Bluetooth interference.
- Disconnect all Bluetooth devices, leaving only the controller connected.
- Adjusted Steam controller settings (the issue persists outside of Steam too).
- Tested multiple games (happens in all of them).
- Updated Bluetooth and adapter drivers.
- Disconnected all other peripherals.
- Updated the controller's firmware.
- Unpaired and repaired the controller.
Does anyone have any ideas on how to fix this?
