literally my whole steam library with 80 something games works with linux. just saying. and they are not some linux specific games either. fallout 4, mafias, baldurs gate 3, the forest, rdr 2, gta v etc.
your opinion is from 5 years ago. when have you last even tried to game on linux? and what are you even doing in linuxmemes with these comments? :D kernel level anti cheat is a different thing though
just go check protondb if you need some proof it has all the games on steam listed with info how well they work
