I wouldn’t be surprised if there was some “AAA” game that was that cavalier about compatibility. I wouldn’t go so far as to say “most” of them do, though.
I’ve seen many large studios and publishers with in-house hardware compatbility labs. There are also lots of compatibility testing outsourcing companies that both studios and publishers will use. Finally, many games come with lists of “feature enable/disable per hardware kind / driver version” blacklist files, developed through testing on various kinds of hardware, and those couldn’t be developed without having the actual hardware to test on.
