Abstract:
A method for determining a resolution and rendering an image, comprising the steps of:(a) rendering a current image frame into a frame buffer at an image frame resolution;(b) computing a rendering time determined by how long it takes to render a previous image frame into said frame buffer;(c) comparing said rendering time to a high-water mark,wherein said high-water mark represents a second rendering time at which an image frame resolution would start to be reduced, andreducing said resolution for a next image frame, if said rendering time exceeds said high-water mark; and(d) comparing said rendering time to a low-water mark,wherein said low-water mark represents a third rendering time at which an image frame resolution would start to be increased, andexpanding said resolution for a next image frame, if said rendering time is below said low-water mark and said image frame resolution does not equal a target resolution.
