Claim 24:
25. A graphics processing apparatus comprising:
an image rendering circuit to render left and right image frames to be viewed by a user's left and right eyes, respectively;
one or more display buffers to store image frames rendered by the image rendering circuit; and
a time warping circuit to perform time warping operations on image frames stored in the one or more display buffers, a time warping operation to transform an image frame in accordance with current sensor data provided from a user/eye tracking module;
a frame selection circuit to determine whether to select a first frame currently being rendered or to perform a time warp operation on a second previously rendered frame to display on a left or right display, wherein the frame selection circuit is to make the determination based on a first amount of time remaining to complete rendering of the first frame by the image rendering circuit and a second amount of time that is already known and that is required to perform the time warp operation on the second frame by the time warping circuit.
