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! -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
