I wasn't even aware that qemu/KVM got this feature. IIRC the device
passthrough worked only for simpler devices like NICs...

IMHO that's expected. I'd guess that both qemu and spice-server would
have to be modified to consume data out of physical videocard instead of
some of the qemu emulated devices.

Standalone spice-server for Windows doesn't exist. It does exist for
Linux but I'm pretty sure it wouldn't be able to leverage GPU for OpenGL
acceleration either. Alon?
