Listmates, ATI, cc:Stefan:

I have downloaded, built and installed the 8-12 release (version 8.561)
of the
fglrx driver on my Toshiba P205D laptop running openSuSE 11.0. The driver
packages builds and installs just fine from the ati-installer:

Also, the driver now supports 11.1, so I presume it will build fine
there too.
Building results in the rpm:


which builds the fglrx.ko module against the kernel source just fine and
installs with no errors. That is where the good news ends. For my laptop with
the radeon 1200/1300 mobile card, the performance of the 8-10, 8-11, and the
8-12 drivers is just terrible compared to the 8-8 and 8-9 drivers.

Immediately before installing the 8-12 driver I was running the 8-9
driver and
dumped glxgears frame rates to compare, again, against the new 8-12 driver.
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

Glad you posted that, I was debating going to 8.12.
I think I will stay where I am for a while.
