I seriously have no clue about anything related to this.

It smoothens out the rough edges, from what I've heard.

but you must have good gcard to use this option because it uses lots of recourses of your card. and slowes the game.

umm... I know this thread is kinda closed but just to brag about :-
AA= Anti-Aliasing- A technique that smooths the roughness in images or sound caused by aliasing. During frequency sampling, aliasing generates a false (alias) frequency along with the correct one. With images this produces a stair-step effect. Anti-aliasing corrects this by adjusting pixel positions or setting pixel intensities so that there is a more gradual transition between pixels.
AF= Anisotropic Filtering- A method of filtering textures using a nonsquare area. With this method, a pixel may encompass information from many texture elements (called texels) in one direction and fewer in another. It yields sharp textures on objects that slant away from the viewing plane, such as a road running into the distance.

Pay attention to the windows of the car, sideskirts and front bumper, rims....
Also the round thing down the car (yellow and black) I have no clue how is it called

... expositor? LOL

AA: 0x

AA: 8x

My gfx card is a bit crap (128mb FX5200), but the AA results are way better in more advanced gfx cards. Specially in the new generation ones (Gforce 6800, ATIx800...)

Hohoho Dani, that's looking waay too good. I can't even turn on the AA on my FX5900 XT, the screen goes flashing.
