Automatic configuration of knobs to optimize performance of a graphics pipeline

Abstract:

A knob has a plurality of settings that configure a graphics pipeline. A first setting is associated with a first state of the graphics pipeline. The first setting is associated with the first state based on a measure of performance of the graphics pipeline while configured according to the first setting. The graphics pipeline is configured according to the first setting in response to the first state of the graphics pipeline matching a current state of the graphics pipeline. The graphics pipeline processes graphics according to the first setting. In some cases, the first setting is associated with the first state of the graphics pipeline by dithering or toggling the knob between the settings once per frame for a predetermined number of frames. The first setting achieves better performance than other ones of the plurality of settings during the predetermined number of frames.
