I'm glad to hear that. Last time I looked into it was when I was first building a PC specifically for KVM virtualization and it wasn't working the greatest then (especially returning the card to host on VM shutdown). Now that it's working better I may make a backup then try to see if I can get single GPU passthrough working. I'm excited by far linux gaming has come and wanna give it a try myself on better hardware.

Are you using single GPU passthrough? I run windows for games and linux for everything else with dedicated GPUs for each. Now I'd like to be able to do some gaming on linux as well because proton has come so far, but my linux GPU is definitely not up for the task. It barely handles hardware acceleration at 1080p without dropping frames on the nvidia proprietary driver and on nouvea it isn't even worth it to try anything higher than 720p.
