Systems and methods are disclosed for low motion-to-photon latency for augmented and virtual reality systems. Some systems generate rendered frames that are presented to a user by outputting light from a head-mounted display unit. The rendered frames are perceived by the user as virtual content. The head-mounted display unit includes an orientation sensor, a display configured to output light to the user, and processors. The processors receive a rendered frame of virtual content, obtain orientation information from the orientation sensor, and warp or modify the rendered frame of virtual content based on changes to the orientation of the user's head. The warped rendered frame is subsequently outputted from the display using modulated light. The processors and the orientation sensor may be part of a spatial light modulator for modulating the light used to present the warped rendered frame. In addition, the spatial light modulator may be a LED array having low persistence and a high duty cycle.
