I must be doing something wrong because a 3060 ti on fedora 41 with proprietary drivers from rpm fusiion was entirely unusable for gaming. Absolutely unplayable performance on X11 and bad performance with steam glitching on wayland.
Switched to amd and it works now
I am only messing with KVM/libvirt for fun so i have no professional experience in this but wouldn’t you want to use virtio disks for best performance?
