  • Patent number: 11354848
    Abstract: Systems, apparatuses and methods may provide for technology that assigns a first shading rate to a first region of a frame. The technology further assigns a second shading rate to a second region of the frame.

The first and second shading rates are associated with a selection based on a motion vector that corresponds to motion of an object. The object is rendered as part of a scene that includes the first region rendered at the first resolution and the second region rendered at the second resolution.
