Running Ubuntu 13.10 stock, I was getting horrible "jitter" across the entire OS. Meaning that, videos would not play smoothly compared to a TV set, Compiz effects were not smooth, games were not fluid as if playing on a console, etc. So I recompiled the kernel with the RT-Preempt patch, and the situation has greatly improved!

However, this patch has dropped the framerate in Netflix (using Pipelight) to unwatchable levels -- about 5-10 FPS by my eyes. Yet YouTube is better than on Windows 7, with the patch.

How could it be that I'm getting superb performance everywhere except Netflix?

I know this is a very obscure problem I am having, but if you have any insight or suggestions, it would be appreciated.
