Hello there,
I’ve installed OpenSUSE 11.4 / KDE on a self assembled PC based on the ASRock P4i945GC motherboard that hosts the Intel Graphics Media Accelerator 950 which is inside the 945G Express Chipset.
The graphics performance seems not so good, in fact:
- at KDE start, a message appears saying that desktop effects are slow and are being switched off;
- switching from a window to another is not fast;
- nexuiz (3D game) at 800x600 resolution with all effects turned off is orribly slow;
- glxgears runs at 50 FPS;
I made a comparison with OpenSUSE 11.2 Live KDE where:
- desktop effects are active and smooth;
- tab switching is faster;
- glxgears runs at 200 FPS;
I’m not so skilled in linux to understand which video driver is used in the two cases.
So I’m asking for help to find the best video driver and eventually install it in place of the current one in 11.4.
Here follows an excerpt from lspci on 11.4:

I also looked into Hardware Information, in both 11.2 and 11.4, searching for useful clues, but could not see anything meaningful to me; here are two excerpts:
