Abstract

A method and system for optimizing image quality while operating an interactive graphics application within a data processing system. First, the image rendering speed for each of the rendering modes available within the interactive graphics application are assessed. Upon initial operation of the interactive graphics system, a default rendering mode is activated. During operation of the interactive graphics application, the processing load imposed on the data processing system is monitored and utilized as a user activity metric. The active rendering mode is updated in accordance with the user activity metric, such that the speed of the selected rendering mode varies inversely with the current processing load.
