View Full Version : Questions about AA and AF

11-23-03, 03:57 PM
I am trying to figure out the best IQ vs performance hit options while tweaking my 5900nu. Can someone please explain the different modes of AA to me? and which one is best? Whats the difference between 2x, 2xQ, etc

Also, is there really a big difference between anisotropic filtering 2x, 4x, 8x? Is setting it to 8x killing performance for a nominal gain in IQ?

Thanks for the help. I've been out of the video card scene for a while and can't seem to find a straight answer to these questions.

Quick answer - best "bang for the buck" for your card is probably 2X AA and 4X AF. Experiment with those settings at resolutions greater than 1024x768. Download FRAPS to check your frame rate.

Most people agree that when setting anisotropic filtering, a setting of at least 4x is needed to really get a significant IQ boost. You should try playing with 4x AF and with 8x AF and see if you can tell the difference between them. While playing with 8x AF note how performance is and whether you think it is choppy or not, and whether you are willing to sacrifice speed for IQ.
