Degraded performance in WarThunder after latest nvidia driver update

MakeTopSite · 11-25-2022, 09:22 AM

FPS is ok but graphics is jerky. Is it please possible to fix it ?

Code:

# inxi -Gxxz
Graphics:  Device-1: Intel 3rd Gen Core processor Graphics vendor: Micro-Star MSI driver: i915
           v: kernel bus-ID: 00:02.0 chip-ID: 
           Device-2: NVIDIA GK107M [GeForce GTX 660M] vendor: Micro-Star MSI driver: nvidia
           v: 470.161.03 bus-ID: 01:00.0 chip-ID: 
           Display: x11 server: X.Org 1.20.3 driver: loaded: intel,nvidia unloaded: modesetting
           resolution: 1920x1080~60Hz s-dpi: 96
           OpenGL: renderer: NVIDIA GeForce GTX 660M/PCIe/SSE2 v: 4.6.0 NVIDIA 470.161.03

Is it any better if you boot the prior kernel?

It's probably shader compilation. I'll bet the driver update invalidated the cache of previously-built shaders. If it's that, then the problem will go away if you keep playing it.

Thank you I will try it.

Trying a prior kernel is for easy diagnosis whether some kernel difference is related to a problem, not intended as a permanent switch that might be less secure.

I understand but I'm still not sure whether it is secure to run old kernel even for a short time.

Solved after some time of playing so thanks
