I currently dualboot to play some non-Wine compatible Windows games with GPU. My host is Linux and I only have one GPU. Would this enable me to have a Windows guest with GPU support on demand? If yes, I'll beta test!

Hi! Yes, it absolutely will. The only caveat with single-gpu-passthrough is that when you are passing your gpu to the VM, you can only use the VM with your main display and peripherals. (The host is still accessible via SSH.) When you shut down your VM, the host returns automatically.

In the "i can only sort of use one OS at a time" sense, it is like dual booting, but the transition is much faster (since there is no reboot required) and, as mentioned, your host doesn't really go away (you can still SSH into it from another PC on your network.)
