Tested on Proton-GE 25 and Manjaro Linux
You need to install protontricks first! (I used yay -s protontricks
since I'm using ArchLinux-based distro)
Then, you need to find your Steam library folder, where the compatdata is stored (use google if you don't know how)
Usually it is in $HOME/.steam/root
- you can assing it into the $steamdir
variable in your terminal:
steamdir="$HOME/.steam/root"
