Reports of better performance in suse 11 with nvidia cards prompted me to switch from SL5.1/5.2 distro’s to suse 11.0
So quick facts and sys specs,
xfx 790i ultra
GPUs = 2 * Nvidia 9800 GX2’s
CPU = qx9770 @ 4.05 Ghz
Mem = 4GB of OCZ 2000mhz
Under SL5.1 i was very unsatisfied with my new machines performance. Mainly because my old machine that did have a kick as graphics card (quadro fx 5600) and a duo core 3.0Ghz cpu clocked about 60 Hz on a GPU intensive simulation and around 26000 FPS on glxgears :-(. Sli or quad sli wasnt working, and even using a the nvidia-xconfig --multigpu=on flag didnt do nothing. I was able to achieve about 18000FPS on glxgears and about 40 Hz on the GPU simulation.
The new machine listed above with suse 11, were now down to 12000 FPS on glxgears and 30 Hz on the GPU simulations.
I just cant win,
I need access to the other cards and their respective stream processors but nothing seems to work.
Really unimpressed, is the hardware just to new?
