If you want this guide to work on the deck, for easiness of following the guide, make your filesystem temporally writable 
and install protontricks regularly.

This is really an update for the guide found here https://github.com/ValveSoftware/Proton/issues/148#issuecomment-585921635

We will be using Proton 5.0-10 the only proton version that works good for assetto.

Before starting, make sure you have no pfx folder for assetto corsa, you can search for it in:
/path/to/your/SteamLibrary/steamapps/compatdata/244210

Execute the game once and let it close
