After doing a cachyOS package update my fps in games have become unstable. I first noticed this in Outlast Trials dropping from 90+ fps down to ~20fps. I have now tested other games and the issue persist. Extremely unstable fps will run mainly at 20fps and the jump up two 100 fps in correspondance with gpu and cpu usage mirroring the same pattern. Super easy games to run will cap at 60 but still stutter infrequently. This seems to point to a rendering queue issue (right?)
Monitoring usage GPU hovers around 20%-40% and will suddenly spike to 90% for a short while before going back down. For the CPU it’s more stable at around 20%-60%.
My best guess is that this is some CPU or GPU rendering queue throttling? I’ve included my pastebin and I guess what could be interesting to look at there is the nvidia driver being used. Maybe there was a mismatch caused by the update? Do I need to do some kind off downgrade (linux noob btw).
Anyone else had this issue? I have not idea if it’s related to the April release.
This issue has just “randomly” come up, I had no problems before. So this really sucks when things just breaks, makes linux and cachy seem unreliable.
EDIT - After reading this post and installing nvidia 32-bit driver. Game ran better for a bit but then regressed.
This is because the new cachyos abandoned the old power state setter for the gpu and cpu. We can check if our components are in power saving mode with
nvidia-smi --query-gpu=pstate
P2
sudo systemctl status nvidia-powerd cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
powersave
Now we see the problem. We can force our components to perform properly again with.
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
This sets all cpu cores to performance mode.
sudo systemctl mask nvidia-powerd. For the GPU.
