as i sayed...the default renderer is sdl/mesa thingy .....software rendere without hardware acceleration. you have to change this in the UnrealTournament.ini in ~/.loki/ut/System
and of course fetch the latest nvidia driver.
i dont have suse and i dont like suse;-) ...but AFAIK there are some special things to get opengl running...
try to run glxinfo in a xterm an look for a line like:OpenGL version string: 1.3.1 NVIDIA 28.80
if its present opengl runs....at least do a cat /proc/driver/nvidia/agp/status (as root)
if you see:
Status:Enabled
Driver:NVIDIA
(or maybe agpgart),the only problem is ut itself
