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:

ati-driver-installer-8-12-x86.x86_64.run

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

fglrx64_7_1_0_SUSE110-8.561-1.x86_64.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.
