What are AA and AF exactly?
« on: October 22, 2008, 12:06:43 PM »
Anti Aliasing: The feature that removes the Jagged lines that are created when you draw a diaganal line on a screen. It removes the jaggies by adding a slightly darker shade next to the pixel creating a blurred effect that makes the image more smooth.

Anisotropic filtering: Is Texture filtering of objects that are far away and usually tilted at an angle the further object is blurred slightly to help the effect of distance. think of the opening titles of star wars where the letters blur as they get further away.


Did anyone know about this??
I didn't  ;D

Hank. I'm definitely convinced that you're a console gamer now. They're just getting around to these things.

Well, I for one didn't know what they were. Now I know that I can turn 'em off if I need a few more fps ;)

I put them in the same category as HDR, some engines do a good job with them some don't.

HL2 do a crappy job of it, COD4 does a good job of it, Crysis does an amazing job of it.

So if your system can handle it, then experiment.

AA is one of those things that, once you've used it, it's hard to go back. That said, sometimes it just doesn't play nice.

For example, Flight Simulator 2004 didn't play nice with my old nVidia card. I had to disable AA in it. It still looked pretty good, but with AA it would have been much better... :(
