It performs really well.

I love qemu/libvirt - the crazy thing is if you have two disks and use one to boot Windows, you can mount the disk then boot into that when using Linux and have that running off another video card (I have two in my PC, one AMD and and nVidia).

This is awesome. In theory you could absolutely minimize the latency penalty to just the overhead of the gpu1->memory->gpu2 copy, if the display sync signals from the display the passthrough window was on were passed through to the GPU driver on Windows, and that was combined with fullscreen compositor bypass (available on many Linux WMs) or low-latency compositing (available on sway and now mutter https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1762 on Wayland).

The problem is that you have to have a monitor plugged in the windows card otherwise it goes all wonky. At that point you could just use a KVM....

The blurb at the top says "allows the use of a KVM [...] without an attached physical monitor, keyboard or mouse." Is that not correct?
