That is good to hear. My results where achived using the 3.9 and 3.10 kernels
although I belive that the hardware and opengl driver affects performance the most.
With such a good hardware and relatively low resolution, you wont see that much of a differance :-),
but it is a nice improvement indeed. Anyway, nice to get additional tests!
