* 1276 FPS for xserver-xorg-video-intel version 2.6.3-0ubuntu9
* 885 FPS for xserver-xorg-video-intel-2.4 version 2.4.1-1ubuntu11~ppa1
kernel 2.6.28-11-generic:
* 177 FPS for xserver-xorg-video-intel version 2.6.3-0ubuntu9
* 420 FPS for xserver-xorg-video-intel-2.4 version 2.4.1-1ubuntu11~ppa1
As you can see, with the default Jaunty kernel, reverting to the Intel video driver 2.4 improves the performance from 177 to 420 FPS (for 2D, you can tell it by playing a Flash in full screen), but the 2.6.30 kernel has two surprising effects:
* improves the performance of the 2.4 driver from 420 to 885 FPS, so roughly 2 times…
* …but the performance of the default 2.6 driver is boosted from 177 to 1276, so more than 7 times!
No need for any newer intel driver! Kernel 2.6.30-rc4 fixes the issue by itself! At least for my [8086:27a2] (rev 03) using EXA.
