8600M GS and OpenGL support

I am running Vista-32 Ultimate using 8600M GS video-card. Using the forum advice I have installed CUDA 2.0 BETA (not CUDA 2.0 BETA2, because for some reason it does not understand this card).

After installing the driver, sdk, and toolkit I am able to compile and run the samples, except the ones that require OpenGL. For those I am getting: ERROR: Support for necessary OpenGL extensions missing.

What am I missing? Please help :argh:
