It's very close to native performance. Only major issue I had is crackling sound, but it's resolvable. In my setup I have second set of controls (keyboard + mouse) to be forwarded to guest and HDMI output of guest GPU is connected to HDMI switch. Once everything set up, it looks and feels like you have second PC under your desk. I use conventional Linux KVM virtualization ("libvirtd" + "virt-manager" GUI) on Fedora 32 (previously used Debian). Most valuable resource is Arch Wiki: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVM... I've never used Arch Linux, however I always refer to Arch Wiki - it's extremely useful even for other distros.
