Vid card tweaks

[SacredTbag]

AA (anti aliasing) is the smoothing out of the edges of 3d objects. all 3d objects are rendered in 90* angles, that's the "jaggies" that you see with AA turned off. what AA does is it "blends" the edges of the 3d object with the surrounding image behind it to give it a clearer appearance. the different level of AA applied depends on how much it tries to blend it. on older gpu's it can be extremely taxing, but most modern gpu's, say made in the past year and a half, can handle it without much of a problem, especially in a dual card setup. just don't try transparency AA on anything except a 8800 series card ><

AF (antistropic filtering) is what keeps textures looking clean the farther away they are from the view point. think of it this way. you're looking down a railroad track. in a game, if you set the AF down low, the cross ties would look muddy and mashed together the farther away they went. with higher level's of AF, they keep their clarity the farther they go.

that's a pretty dumbed down version of them, especially AF. but that's about what it is. the higher the setting, the more your card or system has to work to render it.
