This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for reducing AR
power consumption via bounding sparse content. A processor obtains, for a frame of
graphics content, a first indication of at least one of: the frame, a
graphics processor tracked active pixel region associated with the frame, tile tracking compression
metadata of the frame, or render associated tiles of the frame. The processor computes, based on the first indication, a set of bounding areas for a set of active pixels of the frame. The processor configures a
workload for at least one of a composition or a reprojection on the computed set of bounding areas. The processor outputs a second indication of the configured
workload for at least one of the composition or the reprojection on the computed set of bounding areas for the set of active pixels of the frame.
