10 is way better for games than 7. I’m never touching 11, it’s awful. 10 is great when you debloat, use OOSU10, and use ClassicShell (or the updated version I cannot remember the name of) to bring back the 7-style start menu.
I’m excited to make Linux my daily driver for most things, but for a heavy game-player, a backup Win10 install is a must. Especially for VR.
