I've played around with tons of settings and have installed the latest Xorg,
intel drivers, Mesa, etc. but I simply cannot get the right performance from
my G33 based intel video card that is part of the Gigabyte GA-G33M-S2H.
My only aim is to connect my Philips flat tv through HDMI via 1080p
(24/50/60) Hz and play various type of video (576p, 720p, etc.) using
I simply don't get the performance I need and cannot find errors in my
XOrg.0.log. When playing a simple mpeg2 based video through DVB-T my image
is bad, lagging in some areas especially with panning pictures, but my CPU
(an Intel 6850) is at 10% .
Some metrics: using glxgears I get 1776 FPS, is this any good for 3D?
As you can see in my Xorg.0.log, the 1080p video modes available are 50Hz
and 24Hz. Both should be non-interlaced but at 50Hz, I see a lot of
interlacing in mouse movements for example. My TV should support 1080P at
60Hz non-interlaced but this is not recognized. Also, when running at 24Hz,
the video playback becomes even worse.

Is this simply the Intel driver or hardware not capable of driving my screen
at 1080p or is there something wrong in my configuration?!
