Default 3D acceleration problems with GTS 250 on Fedora 12 x86_64

Hi all!

I have some troubles with my 3D acceleration of my Nvidia Card GeForce GTS 250.

My system is fedora 12 x86_64 (Kernel 2.6.32.11-99.fc12.x86_64) and I installed the Nvidia driver (driver version 195.36.15) like described in fedoraforum.org via rpmfusion.

After a fresh install of Fedora I installed wine and startet WoW. The game starts but I have massive graphical corruptions (so I cant see a thing on the display) and my screen flickers every few seconds. I also tried to activate Compiz, but my screen is flickering, my mouse is very slow and I canīt move the windows. My 3rd "test" was the game Glaxium, but the game crashed every time i started it.

I installed these nvidia packages:

nvidia-settings-1.0-3.4.fc12.x86_64
akmod-nvidia-195.36.15-1.fc12.x86_64
nvidia-xconfig-1.0-2.fc12.x86_64
xorg-x11-drv-nvidia-libs-195.36.15-1.fc12.i686
kmod-nvidia-2.6.32.11-99.fc12.x86_64-195.36.15-1.fc12.2.x86_64
xorg-x11-drv-nvidia-libs-195.36.15-1.fc12.x86_64

glxinfo | grep rendering says "direct rendering: yes"

[root@Melanie ~]# glxinfo
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
server glx extensions:

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GTS 250/PCI/SSE2
OpenGL version string: 3.2.0 NVIDIA 195.36.15
OpenGL shading language version string: 1.50 NVIDIA via Cg compiler

So everything looks fine for me. Nouveau driver is blacklisted in /etc/modprode.d/blacklist.conf and also in /etc/grub.conf with rdblacklist=nouveau.

I know glxgears isnīt a benchmark, but the output is really very bad:

27 frames in 5.8 seconds = 22.000 FPS
132 frames in 5.0 seconds = 26.174 FPS
59 frames in 6.3 seconds = 9.335 FPS
106 frames in 6.2 seconds = 16.969 FPS
45 frames in 5.9 seconds = 7.665 FPS
45 frames in 5.4 seconds = 8.371 FPS
41 frames in 5.0 seconds = 8.120 FPS

Do you have any ideas for me why I have these problems with 3D acceleration.

Thank you for your help.

Melanie
