Abstract: As part of rendering a scene including at least one graphics object in a display space, the display space is divided into a plurality of tiles. A determination is made that contents of at least two of the plurality of tiles are no longer used after a current render pass. A write back memory address associated with a second tile is changed to match a write back memory address associated with a first tile. As a result, data is overwritten on a same physical page.

Abstract: A processing unit includes traversal recursion circuitry that performs, on behalf of a software shader, at least some of the requisite actions for traversing selected types of nodes of the acceleration structure. In response to identifying a first node of a raytracing acceleration structure is of a first type, the processing unit provides an intersection result for the first node to recursion circuitry. In response to the intersection result for the first node, the processing unit performs a traversal operation for the raytracing acceleration structure at the recursion circuitry.
