You don't seem to *want* to understand. It's not about special drivers. Or specialized audio processing. It's about my 3D desktop cube getting skippy sometimes while video is playing. It's about the transparency effect applied while moving mplayer resulting in some frame skipping. It's about a slight pause while scrolling a web page if I have an emerge running. About the mouse freezing for about 0.1 seconds once in a while while doing the same. Can't you understand, or don't you want to understand?
