TIL (and I know I’m late for the party): protontricks
can set the env
for Steam in a very comfortable way to run another exe in the same wine prefix/bottle/compatData folder for an already running game. Useful for companion apps of games or e.g. OpenTrack. I used to do this manually with little scripts 🤓
protontricks-launch ~/.steam/steam/steamapps/compatdata/1069190/pfx/drive_c/opentrack/install/opentrack.exe
