I always hear about AA and i always put it on, but i dont really know exactly what it does...i know it has something to do with distance, right? Can someone explain to me what it does and maybe provide a screenshot? thanks.
 
If you search around there are a lot of websites which give detailed, really detailed descriptions of what it does exactly. Basically it lets textures which are farther away, or skewed (like looking down a road) appear sharper and clearer, rather than being blurry.
 
err thats AF guys he is asking about AA, Anti Aliasing removes jagged polygon lines on edges of polygons in real time
 
Just to let you know, I think you're getting your acronyms mixed up.

AF = anisotropic filtering
AA = anti-aliasing (full-screen anti-aliasing)

EDIT (response to below): this was for original poster. He said AF in the title, but AA in the text.
 
Well then, my bad. I thought he said AF.

In basic terms, AA gets rid of jaggies. Jaggies are evil, and no one likes them. AA destroys them. AA = good. :D
 
Thread title says anisotropic filtering not anti aliasing.

Antialiasing, used to remove "jaggies" that can occur on any edges in a game.

Anisotropic filtering, used to improve texture depth.

Images were robbed from google image search.

Here's a question I have about copyright, say you are an artist and you draw a painting, if someone takes a picture of that painting and sells it, is that an infringement? I would think yes in that case, but what if someone takes an artistic rendering of a building, are they robbing from the architect?

Or perhaps someone takes shot of a game, to demonstrate anisotropic filtering as above? Is that photo their property? Or property of id software as it is their textures arranged in a certain way as defined by their map?

It be fine as long as its not on a website of yours... and claiming it as your own.
