Default Re: VDPAU testing tool

Stephen mentioned to me that various CPU frequency scaling technologies also affect the memory bus clock speed, which affects the memory bandwidth for notebook/mobile GPUs. For these systems, you may need to disable CPU frequency scaling or force it to a particular minimum level to ensure that the GPU has enough bandwidth.
