Bad, bad idea. That'll make your image appear to jitter when framerate 
drops. Headaches guaranteed.

Better have the GPU render to an interim image buffer (possibly at low 
framerate), and have a separate thingumajig do high-speed fixed-rate 
mapping of that interim image buffer to the VR display, taking into 
account the extrapolated direction you'll be facing the very moment the 
image will actually appear.
