I have been going through NeHe''s great tutorials for the past few days, and i was able to get up to the texture mapping tutorial, where i started to notice that my comp was having some trouble rotating a texture mapped cube. So i went and downloaded the demo game, Ravager from NeHe''s site and it was dragging extremely slow...i did the video test and it clocked in at 0.0 fps!!!!! I have a pentium II 400 mhz processor w/128 mb RAM and a voodoo banshee 8 mb video card. I am able to play games like half life, alice, etc fully accelerated w/out a problem, but is there a reason these opengl progs are lagging so much?? Any help or information would be appreciated.

HI there...
I have a computer almost identical to yours... and things run great for me. I have a 16 meg voodoo banshee on a P2 400 and 128 mb RAM.
OpenGL runs great for me!
I think you should get new drivers for the card. go to 3dfx.com and look for them.

Good luck.
