I’ve honestly had better luck with retro games on Linux than windows. Half the time lutris can auto install the game with minimal input, and patch the games etc - and even with abandonware titles I just pointed proton at them after installation and no issues.
If you’re on older integrated graphics however, I will admit it can be a lot more problematic.
Linux is bad at audio therefore it’s bad at everything? Interesting. Fair point about audio though, if you’re doing anything to do with that then stay clear of Linux. Raspberry pi audio is bad even by Linux standards, lol
