As if many Windows games don't work on Linux via proton, to the point that Valve's Steam Deck runs on Linux and is "good enough" most of the time. Compatibility purely depends on the game and more often than not incompatibilities are caused by anti-cheat mechanisms.

And about jumping to Linux: we had Windows computers in my family, originally with Windows 7, then upgraded to Windows 8.1, and once 8.1 was EOL, they were reinstalled with Linux (KDE as desktop environment). Since these computers were mainly used for email, web browsing, and some basic "office activities" like writing a simple document occasionally, there was exactly no issue with it. KDE itself is also similar enough to a Windows desktop that it wasn't hard for anyone to learn the few relevant things that are different. I'd be quite surprised if this was different for the majority of current Windows users.
