@lieff the minimum required driver version is 396.54 ValveSoftware/Proton/blob/proton_3.7/PREREQS.md
@m-svo I'll re-test it with new drivers later. But since game very old, I do not think it's driver related issue.
Same with new drivers.
Crash when starting with Proton 6.3-8 (AMD, Mesa 21.2.6)
Also, when using PROTON_USE_WINED3D=1 I get error about low video memory (0) followed by crash so that isn't working either in 6.3.
