OpenGL runs fine on Win2k.
Chances are you either have bad drivers or you have done something crazy like deleting the opengl32 dll from your c:\winnt\system32 directory.
I’m having problems with my kyro card to. It works fine in XP, but I can’t get opengl or direct3d to work in win2000. I have installed directx 8. This is really bothering me, because I can’t play opengl games in win2000.
