Hello @HatcherMine, there's not enough actionable detail here to do anything with your feedback. In general, most games used with Proton need a sane, working Vulkan driver stack because it uses DXVK to translate DirectX to Vulkan. If the game is 32 bit, and you didn't previously have nVidia's 32 bit userspace libraries, then the only guess I could make is that the game was previously running on the AMD GPU side of your CPU, and you're hinting that some system issue has happened to break the 32 bit Vulkan render path there.
