1. An apparatus comprising:
first circuitry to retrieve image frames from memory;
second circuitry to:
allocate tiles of an image frame within the image frames into different bins,
determine whether a content count of a first bin for a tile of the image frame is over a threshold,
responsive to that the content count is below the threshold, compare content of the first bin with content of a second bin for a corresponding tile at a same location in a prior image frame to determine whether content remains the same between the first and second bins, and
responsive to that the content remains the same, set an indication for the tile of the image frame; and
third circuitry to perform shading on one or more tiles of the image frame that are without the indication.
