1. An adaptive degradation system for selectively degrading quality of rendering a scene, comprising: a rendering module containing a plurality of submodules each capable of rendering said scene at a different quality level; means for monitoring a rate of rendering said scene by said rendering module, each of said plurality of submodules having a different rate of rendering said scene; and means for, during rendition of the scene, after rendering a first object in the scene using a first submodule associated with a first quality level, automatically selecting a second submodule to render a second object in the scene such that said rate of entirely rendering the scene is above a predetermined rate, wherein the second submodule is associated with a second quality level that is different from said first quality level.
