To all my knowledge that's not a video card specific thing, but a 
general part of the Oculus API. (The application/game must be written to 
support it though.)

For this to work best though, the framerate (and hence the lag, which 
still exists) needs to be known so that the head movement can be 
extrapolated into the future.
