I recall setting up wine for the original World of Warcraft. That was such a pain to do. Performance was great.
Running games on Linux now is easier than I ever could imagine. Especially with steam and the other launchers added such as Lutris.
Been rocking the game Grounded on my steam deck while my kids are on their windows machines. And it has great performance even output to 1080p monitor.
I agree it seems like most the comments are from people who haven't even attempted to run games on it. Or maybe there attempt was just to double clicked the setup.exe and it didn't work like windows and they threw their arms up and walked away.
Just discovered it after the big patch came out in November. Fun game. The OP can just find out lol
