Log files

Please attach Proton or Wine logs as a text file:

  • When using Proton, set the Steam launch options for your game to `

steam-1903340.log

and attach the correspondingsteam-xxxxx.log` file in your home directory.

  • When using regular Wine, use wine game.exe > game.log 2>&1 and attach the resulting game.log file.

If there is anything I can help with to test and diagnose why the big difference (or maybe it is already known but not by me), then let me know how to help.

This is extremely well known and there's a million other mentions of this.

Thank you buddy. Thought maybe in the files there could be something helping you with it. I was not aware it was something we'll known since on some cases it happens and on others it does not.

DX12 performance issues on NVIDIA are extremely well known and we're all waiting for NVIDIA to do something since unfortunately it will most likely remain impossible to fix otherwise.
