I know this isn't exactly what you were saying, but I recently bought myself the (ancient) Star Wars Empire at War games, and they run better under WINE than they did under Windows 10. There's some problem that makes it drop frames and become unplayable in Windows.

Moreso on topic, I actually do much of my gaming in Linux, I only have a couple of AAA titles that I use Windows for (Elite: Dangerous and AC:Origins), everything else is Linux (KSP, X-Com, X-Com 2, RimWorld).

I often try and make a point of emailing a "Thanks for supporting Linux!" to the companies who release the ones I want to play, just so they know we are out there.
