1. A method comprising:
receiving a stream of rendered frames;
applying an early stage reprojection to rendered frames in the stream of rendered frames at a rate which is lower than a field rate of a display, thereby correcting for a delta between an initial pose prediction and an updated pose prediction; and
applying a late stage reprojection to fields of the rendered frames at the field rate, thereby compensating for remaining pose error that is present after application of the early stage reprojection.
