Edge cases? There's a long history of brand new triple A games running poorly or not at all on Windows. Evstablished games have plenty of problems. There are millions on millions of support pages, forums, and the deep dark recesses of discord stacked with Windows gaming problems. Just because some folks don't have problems with Windows doesn't mean the problems don't exist. The windows user base is so vast it's easy to think there's no problem just because an individual doesn't see it in their little corner of the world.

I don't disagree but when the conversation is about red alert 2 and steering wheels and the response is nobody uses those, then it isn't valid to use the argument that Linux is useless when it runs everything.
