I recently set up 2 gaming VMs using libvirt KVM with GPU passthrough on my Ubuntu install so me and my girlfriend can use the same computer to play games when she comes over. I played a couple games of deathmatch and casual on this setup on cs2 and today I discovered I have been banned. This never caused any problems before on cs:go so I figured it’s fine as this isn’t specifically prohibited by valve either as far as I know.
Are you running it on a hdd or ssd? Had it first on my hdd and it ran like crap, after moving it to my ssd it runs like a charm with (mostly) no fps spikes (running an 6900xt though). I only have the bug that after playing one round i have to restart the game, otherwise the sound gets a >1 sec delay what is really annoying
