Halo anti-aliasing and anisotropic filtering?

Ok ive heard before that halo didnt support anti-aliasing and anisotropic filtering. What if i set it to do it under the 3d tab in the catalyst control panel. Will it then do it?and how do you tell if a game is opengl or direct3d?

 

I believe if you force them on from the control panel they will either wont work OR the game will CTD

 

I've heard if you turn it on you get Halo: The Slide Show. The game engine was never designed with them in mind.

 

Thanks for the input i tryed turning it on in the panel and the game still ran but I couldnt tell any difference.
