Right, the G965 eliminated the overlay so the driver provides only
textured video. It would be fairly easy to stick a spin loop into the
server blocking for vretrace before painting a frame of video; I don't
like to do that in general because of performance issues, but it might
be worth a try to see if that eliminates the tearing issue.
