Maybe Windows fans holding onto one of its last remaining advantages? I have a Windows desktop solely for games. I’d be 100% done with Windows if all the games I play worked flawlessly on Linux
Not technically divesting myself of windows, but having it abstracted from my bare metal will give me a certain peace of mind and smugness. I think anticheat freaks out on one or two games I don’t play doing it like that.
The reason I gave up is because most games that I want to play but don't work is down to anti-cheat software.
Once Valve incorporated Proton, it was all over for Windows for me. I already used Linux (Debian/Devuan) full-time at work on my laptops and servers.
I don't miss Windows at all. Running Devuan right now on an AMD B450 with a 5600, 64GB RAM, and a 1080ti.
I will admit that video driver updates are a little more involved than on Windows, but since I don't have a mainstream Linux distro like Ubuntu, that's to be expected.
If you're willing to pair Linux with a gaming console, you get coverage that's more than good enough for me.
