There's also Proton-GE [1], which is even more experimental and adds some bleeding edge fixes and features.
I've heard it's pretty good for fixing video playback/rendering (e.g. cutscene) issues if both the stable and the experimental branch of Proton can't make it work.
A lot of what Proton-GE brings from my understanding is a larger support for Media Foundation, which can't be added to Proton itself because of license issues (Proton is from a commercial company, where Proton-GE is from an individual).
So aside from the stuff that has been implemented differently, running Proton instead of Proton GE is like trying to game on Windows N editions.
