Re: Video tearing fix for Intel 965 GPU.
« Reply #1 on: November 21, 2010, 09:22:34 PM »
I have an Intel GM965. I had the same options except I have UXA instead of EXA. I had also forgotten to add INTEL_BATCH=1 into /etc/environment after my last install. I am not sure what video 'tearing' looks like. I am sure I've seen it, but blamed in on bad quality video. What exactly does it look like and how can I confirm if this makes a difference for me?

I hadn't notice, but admittedly I don't watch action videos. Mostly news, documentaries, music. I did notice an increase in glxgears, though.

Hi.

I am tempted by this altho I dont have a video problems with my card when watching nonhd videos. I know that the card can do better tho so I will give Your solution a shot with this card:

[andrzejl@wishmacer ~]$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)

This performance is with the KDE4 desktop and the effects switched on. Basic ones. Nothing like wobbly windows, fire, 3D cubes and stuff.

2120 frames in 5.0 seconds = 423.881 FPS
2077 frames in 5.0 seconds = 415.308 FPS

No improvement at all. Maybe due to the simple fact that my card refuses to use any of the options... Stubborn ba...fic card...

All I can do is wait for newer xorg and intel modules to be added to PCLinuxOS altho I can live with the results I have now.

Ha! I typed in your command and got the same result! I think the command that made a difference in glxgears was adding INTEL_BATCH=1 to /etc/environment. I've done this before, but forgot on the last install.
