Have you setup your gfx card to enable 3d?
I know when I first installed any linux distro 3d wasn't enabled (standard card drivers), had to download the drivers from the nvidia website and install via their shell program.
If you know 3d is enabled then ignore what i'm about to say.
Open up a shell console and type glxgears you'll then see another screen open with some gears spinning and it will tell you the fps etc. If its fast then 3d is on, if its going slow then try getting the latest drivers.
Also, do you have a tv connected or just using a monitor?
