Hi, been a while.
I’m not really asking for direct help on this: I installed the 550 driver from the .run file, so I can just sit on it for a bit. This is more what can I do to help you all fix this issue, so I can go back to using a driver from the package manager.
Games appear to crash with both DXVK and VKD3D when NVIDIA is the graphics renderer and an AMD is the primary Xorg renderer. This happens after a seemingly random amount of time spent in the application. I’ve seen it crash almost immediately, sometimes it takes 2 or 10 or 15 minutes or more to crash. The crash manifests as the application freezing, the audio thread carries on for a second before it realizes the rest of the application locked up, and I have to kill it myself in a terminal or through Steam. When NVIDIA is the primary Xorg renderer, nothing appears to break (although for my setup this is undesirable).
modesetting, intel, and amdgpu Xorg drivers appear to make no difference. Disabling my Intel CPU’s turbo and running at base clocks didn’t help. Running the application in gamescope fixes the issue (but is undesirable since I gain a lot of frametime.) Switching from CachyOS (Arch derivative) to Fedora 41 didn’t help. Using the latest lts kernel doesn’t help.
565.77 appears to have this issue, and 550.142 does not. I’m not sure what drivers in between are problematic, but the issue is more recent than not if my memory serves. I figured that after all the troubleshooting I did, if downgrading the NVIDIA driver clearly fixes it, then there’s the smoking gun.
dmesg, journalctl, dxvk’s log, and Xorg’s log have thus far been empty with regards to this, but I can still upload one of those if needed (especially if someone can help me enable more verbose logging on any of those).
The games I have tried thus far are HELLDIVERS 2 and Lethal Company, which are Windows applications. HD2 in particular I can run with either DXVK or VKD3D. I’m not sure I know of a native, intensive Vulkan application to test that I have.
