3d is broken by ATI in the 8-12 release. Go back and download the 8-9

Then build the rpm

Hmm. Tried that. Still disappointing, though. Around 210 FPS on glxgears.

Actually, I think that's the version I had installed from the ati
repository, anyway. So it's no surprise there's no change.



That's strange. I have run direct comparison tests between the 8-9
drivers and
the later versions and posted the results to the list. For my x1300 based
laptop, here is the 8-9 v. 8-12 data:

With the 8-9 driver:

23:43 alchemy:~> glxgears
4889 frames in 5.0 seconds = 977.692 FPS
4870 frames in 5.0 seconds = 973.831 FPS

With the 8-12 driver:

23:59 alchemy:~> glxgears
3021 frames in 5.0 seconds = 604.191 FPS
2613 frames in 5.0 seconds = 522.544 FPS
2614 frames in 5.0 seconds = 522.795 FPS

For my 9600 mobility radeon, the differences or more dramatic. 2600 FPS
8-9, 900 FPS with 8-10 to 8-12.

I don't know what the heck ATI has done to bork the driver, but I
suspect that
new additions to the driver to support the 2400, 3000 and now 4000 series of
cards has had a negative effect on the linux driver.

Looks at the download size of the latest ATI install package. Over 78
You've got to be kidding me. I hope the 9-1 driver has pleasant surprises in
