摘要: A system and method are provided for reducing the number of depth clear operations in a hardware graphics pipeline. Initially, a frame count is stored into a frame buffer associated with the hardware graphics pipeline. The stored frame count is associated with a pixel. A depth clear operation is then performed based at least in part on the frame count utilizing the hardware graphics pipeline.
