just saw something i don't think was ever mentioned.
Just saying that myself and others on this site have mentioned the extremely poor performance (1-6 FPS or so) of standard OpenGL drivers.
Yeah, no duh. The standard XP drivers are software emulations of ogl, simply to promote DX in favour of ogl. At that point it doesn't even matter what card you have, its gonna be dog slow. Which is why you need drivers from the vendor to expect any decent fps. As far as i know there's no problem on linux/mac as they use ogl by default anyway.
