After this script with GE Proton still had the sync issue, it let me get an hour into the match before that tho. I was able to play through shorter matches no problem.

I've modified this to be a generic version of this to work with most other games by passing the APP ID. Also collected some additional examples for users so they don't have to edit the file directly (they still can though)
