Patent Title: Dynamic balancing of graphics workloads using a tiling strategy

Abstract: A method of generating graphic images on a display device of a computer system, by dividing the viewable area of the display device into a plurality of tiles, assigning each of the tiles to respective rendering processes, rendering a frame on the display device using the rendering processes, and adjusting the sizes of the tiles in response to the rendering step. The method then uses the adjusted tile sizes to render the next frame. The tile areas are preferably constrained from becoming too small. The adjusted tile sizes may optionally be smoothed, such as by averaging in weighted sizes from previous frames. The tile sizes are adjusted by measuring the rendering times required for each rendering process to complete a respective portion of the frame, and then resizing the tiles based on the measured rendering times.
