LinuxQuestions.org - ati 9800 distortion

hello everyone! I've searched around for an answer for a few days, so if I've missed something and this is already a thread I appologise =)

I have an ati 9800 that I installed and it *mostly* works. I used the drivers directly from ati and enabled FSAA ( =4) and for the most part it works. On some of the screensavers though, it just desent work. Some of them get between 0.3 - 4.0 fps (thats point 3 fps :). Some get acceptable fps but have distorted graphics as seen here:

Euphoria
Bitmap_Flag
Endgame
Flipscreen

I'm fairly new to linux, so I'm likely missing something silly. I hear that ati deosen't work so well with 'nix so if its just a case of that, then, err, I guess thats all there is to it. But any info that can help me solve this will be greatly appreciated!!

glxgears
5553 frames in 5.0 seconds = 1110.600 FPS
6577 frames in 5.0 seconds = 1315.400 FPS
6575 frames in 5.0 seconds = 1315.000 FPS
6585 frames in 5.0 seconds = 1317.000 FPS
-- however after I installed the drivers and before I turned on FSAA the average for glxgears was averaging ~4400 FPS

blockgear
at full screen with reflections turned on it averages ~52 FPS which is exactly where it should be. Prior to installing the drivers this averaged ~4 FPS with reflections turned on.
