> Unfortunately, I have not had the same luck as @Lolzen. I performed the same system update and performed another reboot for luck but none of the Proton games are working, yet. Same error appears in Steam log.

Neither have I, still the same error.

btw, I have noticed that I was wrong about Middle Earth: Shadow of Mordor not running - it was Shadow of War not running, clicked the wrong one in the library. Apparently Shadow of Mordor is running Vulkan natively (and works), but Shadow of War is Windows only, so it's run through Proton.

I also tried out Left 4 Dead 2, as it runs natively on Linux and Valve recently patched in Vulkan support through DXVK - that one works just fine, so @ArmedAviator might be right that the issue could be closer to Proton itself.

I don't know that much about Proton so I'm still kinda puzzled, as to why it would only break with the newer, xbps packaged driver version, as the old one and the version from Nvidia's website are/were working perfectly fine with the same Proton versions.
