Your card (or at least your driver) does not support OpenGL 2.0. Upgrade, or live with the warning. The game still runs fine. You just don't get any fancy effects. Good luck,
Hi, wanted you to know that I bought me a new box: AMD64 with a nvidia card. Quake2world compiled without any problems on Debian Etch and gives me 500-1500 fps :-D
Haha, nice. Glad to hear it looks and runs as it's supposed to for you now. If you're looking for a game, join the IRC channel. There are usually between 20 and 35 people there depending on the time of day.
