Would be brilliant if some1 at ATI could swap their AI shaders in a way everything works with CAT AI enabled and to advanced too because performance really gains through that. i bet some1 @ ATI loves our game too, and probably it is someone with a long ass shader writing experience... as a fact, they are the only ones who can write really fast shaders for their Radeons, as it is them only who really know the chips and its instructions etc. pp. - see, not even a driver-compiled GLSL shader is as fast as a good handoptimized counterpart, this is why I don't like the whole "C for shaders" language crap, they all get replaced by ATI and nv anyway if the game turns out to be halfway popular. I don't understand how "old-ass" doom3 assembly shaders can run on newer hardware that has completely different registers and so on than say an r300 (9700) that it was written for back in the day anyway. It must be driver-translated somewhere, so it could as well be _all_ replaced, which is what cat ai advanced does. BUT worketh it should. gouthdammit!!
