Low FPS / Performance in Games (no performance issues with fresh OS)

Hello together,

I've bought a new GPU (RX 6700xt) recently and installed Garuda OS for the first time.
I was very happy until a few weeks ago the game performance in multiple games dropped heavily, and I couldn't understand why.

For example:

  • CS:GO: 30-60 FPS (low settings, full resolution)
  • Cyberpunk 2077: ~10 FPS (GPU is at 99%, CPU at 10-20%, ultra settings, full resolution)

These games were running very smooth before.
Before what? I don't know.
I've installed and tested a lot of software, made updates and changed settings since my last game session.

The other day, I found out that it's not the hardware that's causing the problems, since I was able to play at full performance again via a fresh Garuda booted from a USB stick. So it really seems to be the software.
I tried many things to fix it myself, due to the lack of knowledge / experience I may make it worse.

Funny thing: yesterday it worked magically - I had full performance in both games again.
Today it is back to the old.
I have not done much since yesterday.
Basically, I just made Backups via Vorta/Borg & Timeshift, did the updates via KDE Discover (offline updates) and mounted my NAS via etc/fstab.

What I tried so far:

  • searched for related topics
  • boot other kernels
  • updating UEFI & resetting / changing the config
  • different Wine / Proton versions
  • enabling "Disable CPU vulnerability mitigations" with "Garuda Boot Options" (seems not to be saved, other options like the kernel to boot are saved tho)
  • enabling performance mode via "CoreCtrl" for the GPU
  • setting performance profile via "cpupower"
  • disabling Compositing globally
  • closing unnecessary programms running in the background for testing (screenshot tool, opensnitch)
  • wiping ~/.wine & ~/.cache

This is not a bug. It's best practice if you reinstall your os after a hardware change. Watch this video to learn more

I did. I've installed Garuda after installing the new GPU. :v:
My old system was Manjaro.

I’m actually not sure about this, but there must be some kind of directory where generated files are stored? Like wine prefixes. Sometimes deleting ~/.wine helps with issues, so it might here as well?


What is your username referring to btw?


Good idea, but I don’t think it will fix that one problem, because CS:GO doesn’t use Wine/Proton.
Unless it is one problem - which I assume - and not several. Of course, I will try it anyway.

Edit: I’ll try wiping ~/.cache too.
Edit2: Unfortunately, neither of these changed anything.


What is your username referring to btw?

It’s nothing special - just the name of my PC (LinuxGamingMachine). :grin:

What kernels did you try? Be sure to try something that is not on 6.4. Generally we suggest trying the LTS kernel, which is well-supported and runs the 6.1 version.

Another thing that might be worth a shot since you have a very new GPU would be to switch to the upstream experimental build of mesa.


If it does not help I would suggest switching back because there is always the possibility the bleeding edge stuff can introduce new bugs.


Hey, good news! Your idea to boot a 6.1 kernel seems to be the solution!
The performance is not as good as before the issue, but way better than with the issue (6.4 kernel?).

CS:GO: 100-250 FPS and Cyberpunk 2077 40-50 FPS

I'll experiment with other kernels later and try the experimental build of Mesa too.
I will report back if I can achieve relevant improvements so that others affected can learn from it.

Thank you all for your input!


Ok, here is an update:

I've tested more kernels (6.1-4.x + the experimental 6.5 rc) and installed mesa-tkg-git (mesa-git would not build because the source seems to be down [504 @ gitlab.freedesktop.org]).

Unfortunately, I have not been able to make any improvements.
In fact, the kernels based on version 6.1.x are the only ones that don't have the bug and make many games playable at all.

I hope that this bug is known to the developers and is not a very specific, non-reproducible one.
I wouldn't know how to reproduce or isolate it, anyway. :face_with_diagonal_mouth:

Hello again, last update:

the bug has to do with the monitor refresh rate.
When I set the refresh rate below the max. rate of 165 Hz, I can play even with the newest kernel without performance losses.

I will edit the first post to mention this workaround and change the topic.
Edit: Never mind, I can't edit the first post anymore.
