1. 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, in response to a frame completion marker being met; and
a circuit to transform image frames stored in one or more display buffers based on most recent sensor data to track user movement, the circuit to alternate between transforming image frames for the user's left and right eyes based on depth information of pixels and the user movement, in response to the frame completion marker being missed.
