Nouveau driver is not supported i think. You should try with official NV prop driver.
Dont use NOUVEAU for gaming, its just bad
Hello @KSXGitHub, we're using one issue report per unofficially supported game title, and usually I'd transfer this issue report to #4230, but it's fairly obvious that your issue is due to a general lack of Vulkan support in your video driver. Proton requires a spec-compliant Vulkan video driver for most games.
