Install DRM Free game on SteamOS

  1. Switch to Desktop Mode
  2. In the desktop mode, open Steam, and add the installer as non-steam game to Steam
  3. Go to Properties > Compatibility, and enable "Force the use of a specific Steam Play compatibility tool", and select Proton Experimental (or latest stable version, like Proton 9.0-4)
  4. Click Play, it will open the installer, just install as usual.. it is recommended to change the installation folder to not have any space in it
  5. After the installer done, you can find the result in /home/deck/.local/share/Steam/steamapps/compatdata/<gameid>/pfx/c_drive/..., you can sort by created date when looking for the gameid, newest one should be the one you're looking for
  6. Now, Open Properties again, in the Shortcut, you need to change "Target" to the exe file your game is, and make sure to change "Start In" too to the directory your exe file is
  7. Change the name, and done. You can now Play it without any 3rd-party launcher
