The speed of the player graph is under control of the renderer (video renderer, audio renderer, streaming, etc). Disabling UseClock lets the player run at maximal speed. This is used mainly e.g. to play a clip at the processing speed, e.g. to analyse the video frames without dropping any of them because of the player speed.
