Symptoms

When I try to launch a Unity game with Proton outside of Steam with the following command: ~/.steam/steam/steamapps/common/Proton\ -\ Experimental/proton run /game/path/here.exe, this error appears.

If I run the games with raw wine (latest from my package manager), most games seem to at least launch, although they have poor performance or major graphical glitches.

In games that show the Unity resolution selector window, the same error appears for all combinations of the resolutions and the fullscreen setting.

Reproduction

Try launching a game with the command mentioned above.

Proton 5.13-4 and Proton Experimental are having issues launching games outside the Steam, 5.0-10 works fine though. Can you try 5.0-10 with the same command and see if the error still persists?

So far I only tested with Ori and Getting over it, but it seems to work fine! Thank you.

It's a shame that we can't launch games outside of Steam with the newest proton.. :/

@F1xteR Thank you for this! I was having the same problem, and running on Proton 5.0-10 works fine. Thanks again!

To anyone having this issue, try adding __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia %command% to your launch commands.
