I have issues with World of Tanks and The Witcher 3 Wild Hunt.

In WoT game seems to not fully utilize my GPU (in Windows my GPU was constantly at 99%, with 250 - 320 fps). On linux I have constant drops to 80 - 120fps and somtimes even lag spikes. Those lags mostly happen in the beginning of the match, then the game runs fine, but on some maps low gpu usage and low fps are present whole match.

In The Witcher 3 I have performance issues, (on Windows I played with every option maxed out (UBER +) and HAIRWORKS ON set also to max getting about 160 - 180fps. On linux those options make game run sub 90fps. With hairworks disabled I can obtain 90 - 110 fps in dense forest areas (on Windows 200+ fps) or about 160 - 200fps in Novigrad (CPU intensive scenario) (on windows 190 - 250fps).

Both games suffer from huge performance jumps (in WoT somtimes jumps from 80fps to 320fps).
In Witcher 3 from 100fps to 240 fps.

Already tried:

All of latest proton versions (Experimental,GE,EM etc.)
Esync/Fsync/NTsync
WINE XWayland and WINE Wayland
Gnome/KDE.
Switching to scx_ladv scheduler (this actually made the performance worse)
Switching to LLVM shader compilaton.

Proton Experimental seems to work a little bit better than others.

There seems to be something wrong with gamemodeauto.

Try getting rid of that (or at least reinstalling it).

Already tried with gamemmode on and off, issue still persist.

Then I can't really help you. It's some kind of setup issue but the logs don't tell us anything beyond that.

Well, it looks like it's some kind of issue with the graphics drivers itself, I will try reporting it to Mesa and see what will happen. I tried The Finals which is VKD3D game and didn't have any issue so I guess it's some issue in Mesa or between driver and dxvk (on RX 9000 series).
