Setting up looking glass itself wasn't much of a problem though. I got some AAA games cutting on my gentoo laptop like butter, though the mouse movement was more jelly unless I VFIOd my mouse/kb as well. Sound went through Scream over a socket.
Nowadays I play on my Xbox. I ditched gentoo. I've gotten old. Do you, reader, assume that I've also checked out and gone full windows?
If you do, then guess again. I'm about to port my whole gentoo gaming setup to NixOS and it will probably take me about 15 minutes, and ~ 5 - 10 minutes a year just to maintain. How much time do you spend fiddling with your windows and driver updates? Oh, wait...
