I don't know if your drivers are up to date, but I think your card does support OpenGL, if I remember correctly.
EDIT: Or not. I'm not quite sure.
Anyway, I have a question of my own: HOW do you connect? The link you gave me just gives me a generic single player level, so I can't talk.
I tried making my own server then connecting from there, it tells me I'm not the admin.
So I use the console to make me an admin, and try using /goto niffworld in talk. Unrecognized command. Okay, how about in console? [console] admins goto niffworld. Nothing happens.
Seriously, how is it THAT complicated?
