Low FPS after upgrading Fedora to 39

Your system information

System information from steam (Steam -> Help -> System Information) in a gist: https://gist.github.com/kjarosh/00bf2ebbc4f5ec423ba2cb60541176be
Have you checked for system updates?: [Yes/No] Yes

Please describe your issue in as much detail as possible:

Game is unplayable due to low FPS. It is especially evident during combat, looking at smokes/flames, spraying but it is not consistent: sometimes it lowers FPS to like 30, sometimes to 5. This starts happening as soon as the game is started, restarts do not help at all. Usually on spawn and far from enemies the FPS is high.

This started happening right after upgrade from Fedora 38 to 39. Fedora 38 newest updates — no issues, as soon as I upgraded to Fedora 39 it started happening.

Steps for reproducing this issue:

Play the game on Fedora 39.

Perhaps you should reset the Vulkan shaders and recompile them, because after the Fedora update, Mesa was most likely updated as well

Thank you for the suggestion, but it did not work. Cleared the cache, recompiled them, even reinstalled CS2, nothing worked.

Right after recompiling shaders the performance got even worse (longer stutters), but it got to the baseline (the issue description) after playing some time.

Same here, after updating to KDE Plasma 6.0.4. FPS are really low (30-5) but after one day it got back to a baseline. Weird!

EDIT

After a reboot the issue happens again.

Gathered some console logs from today's game. I was expecting to see the output mentioned in the release notes, and that's the only thing I found in the console. Not sure how helpful this is though...

I did not see any other logs related to performance despite me having pretty horrible performance momentarily multiple times (during seeing enemies, smokes, molotovs, etc.).
