I installed the game via Proton. Seems it is still very buggy in wine. I had to follow the instructions here [1] to get it to load without crashing or constantly changing the screen between windowed and fullscreen. Once I got it working the menu was working fine, no lag.
SystemPack for Gothic fixes everything except crash with music enabled, for which native dmusic helps.
I'm suspecting you are either experiencing a wine bug or you have some bad settings somewhere rather than a Mesa bug.
But how does LIBGL_ALWAYS_SOFTWARE=1 (with llvmpipe) help with laggy menu and why it sometimes give more FPS than radeonsi?
I don't have any relevant environment variables set, and only X configuration I have is
Section "Device" Identifier "AMDgpu" Driver "amdgpu" Option "VariableRefresh" "true" EndSection
but laggy menu was there before VRR support arrived.
