Anti Aliasing DOES NOT fix bad texture.
I swear to god. Some people have no idea what they are talking about.
No amount of AA is going to make a muddy blurry texture look magically better.
If ANYTHING AA is only going to make jaggy polygons look smoother.
On the OTHER hand
But it basically takes samples (of which you can change the multipliter) of pixels and aggregates colour values to smooth them out.
High levels of AA can make things look very blurry.
So with AA enabled your bad textures will just look like blurry bad textures.
Wrong. conventional AA doesnt blur textures, only the edges surrounding the polygons. removing the jigsaw effect , or as some people call them "jaggy's" . has nothing to do with the actual textures themselves.
