In the best case, the CPU is still decoding the input stream and filling the display pipeline. If the CPU is too slow, or the decoder latency cannot be anticipated, the decoded results will come too late and frames get dropped. The GPU is also often not suitable to decode something like MPEG or there is only a separate decoder that isn't supported. Then the decoding is done on the CPU as well. With modern CPUs estd usually works better with an aggressive setting, i.e. go to max CPU clock even under low load and fall back to min CPU clock when idle.
