protondb is a community project and is not official. It is still a good ressource though, but it's worthwhile to read comments. 1 - I'm actually surprised about that, it's working much better on Linux than when i had windows where it was really often a "crossing fingers experience". Granted, i haven't used windows for years, so i hope it's in a better state now. 2 - i had some suttering when i was using the llvm backend for shaders (i have an amd gpu). Since i switched to ACO (which is the default in mesa now) i just have one games with suttering, Heavy Rain. 3 - The only crashing game i had was C&C, it seems it was more an actual bug of the game, it was fixed after the game was updated, not proton. 4 - don't use discord so can't comment there. I've finished quite a few games using proton/wine and what you describe is definitely not a generality at all (appart from discord which i don't use, so can't comment).
