I ran the installer again and managed to get to the settings to change it to GE-Proton8.3 (found to have better performance and compatability) 2 things
Inside the tool I had to apply that to every single game and save manually and individually.
Also now I get this error (image)
The game is p3r which does not need proton to run. None of the games on steamdeck require proton to run only some non steam games like emulators ect. Is there a way to sort this?
You're confused. Every game on steam requires proton to work with the steam deck. P3R works perfectly fine for me.
