1. An apparatus comprising:
a first interface to couple to a memory to receive a first image frame rendered at a first point in time in response to execution of a virtual reality (VR) application; and
processing circuitry coupled to the first interface to access the first image frame, wherein the processing circuitry is to produce a reprojected image frame through: a time warping operation that comprises adjusting the first image frame based on motion data indicating motion of a user's head or eyes between the first point in time and a second point in time, and a lens distortion correction operation on the first image frame,
wherein the reprojected image frame is to be displayed.
