Run non steam windows game under Linux
For example I want to run caesar 3 windows game.. Create this script in Caesar 3 folder, named c3.sh $ vi c3.sh #!/bin/bash SCRIPT=`realpath $0` SCRIPTPATH=`dirname $SCRIPT` export STEAM_COMPAT_DATA_PATH="$SCRIPTPATH/compatdata" mkdir $STEAM_COMPAT_DATA_PATH # change this to your proton binary, for example: $HOME/.local/share/Steam/steamapps/common/Proton 3.16/proton PROTON="/path/steamlibrary/Steam/SteamApps/common/Proton 3.16/proton" # change c3.exe to your game executable EXE="c3.exe" "$PROTON" run "$SCRIPTPATH/$EXE" killall -r "$EXE" $ chmod +x c3.sh Run Steam, open menu Games -> Add Non Steam Game -> Browse... and choose c3.sh Click Play to run! 😼
