One issue i have with Proton is that it seems to run these popular games fine, but when faced with something more obscure there are issues left and right. For example recently i installed Arch on my GPD Win 1 (which is essentially a much weaker Steam Deck that comes with Windows 10) and tried: * RoboBlitz - it needed Ageia's PhysX installer which always failed to install at startup * Clive Barker's Jericho - Didn't start at all * Cherry Tree High Comedy Club - Worked fine (but it is a very simple 2D game so i kinda expected it) * Mars: War Logs - It started but 3-4 in the game (actually during a cutscene but was rendered using the game engine) always crashed at random points * Blood Knights - Worked fine * Marlow Briggs - Didn't start at all * Chaser - Didn't start at all All of the above work under Windows 10 fine which makes me suspect that Valve is just going to make game-specific patches for the next Proton in Steam Deck. After all being able to play "the entirety of your library" sounds implausible when you can't do that even under Windows :-P (many games - especially older games - need custom fixes, etc).
