Compatibility Report

Name of the game with compatibility issues: Ori and the Will of the Wisps, Among Trees, Firewatch, Getting over it, etc...

System Information

GPU: RTX 3070 (also tested on GTX 1060)
Driver/LLVM version: nvidia 455.45.01
Kernel version: 5.9.14-2-MANJARO
Link to full system information report as Gist:
Proton version: Experimental

I confirm:

[x] that I have checked whether there are updates for my system available.
[x] that I haven't found an existing compatibility report for this game.

oriwotw_d3d11.log (I don't have a steam version of this game, so this is the only log I got)

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!

Having the same "Couldn't switch to requested monitor resolution" issue using proton 6.3-5 for "mini motorways". Works fine using proton 5.0-10.

I'm having the same issue no matter what proton version I use.
GPU: RTX 2080 Ti
Driver: 525.60.11-2

I'm having the same issue with Far: Changing tides using proton experimental or 5.0-10

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

I'm having the same issue as @SparkyTD in OP, running latest nvidia drivers on Ubuntu 25.10 (latest kernel). Trying to play Ori Definitive Edition

@IgnisFlamme 's suggestion didn't work for me, and trying to force anything DX9 related crashes because DX9 can't be found.

Is this a wayland compat issue?
