I run the game on both a 10.0 SuSE pro (office) & 10.1 OpenSuSE (home) system with the latest NVIDIA drivers from their site ( not the rpm package).
The only glitch up to now is that under xgl, the game does not work.
But I think that I can attribute it mostly to the fact that my VGA card is not fully supported under linux from NVIDIA. ( NX 7950 GT)

So I would suggest to view the NVIDIA options through sax2 or YAST.
Else try to install the binaries from nvidia site. ( Though they claim that installation should be done through YAST, I find extremely easy to do it through their binary. The only drawback is that after a kernel update I have to re-run the package.
I hope that I helped you somehow
