What do AA and AF do ????

[AMDX23800+]

Hi ,
What exactly do the AA and AF options do in games, is the difference very noticeable ?
Thanks

AA smooths out the jaggies you get in straight lines and AF increases the image quality.

EDIT: Here's a detailed explantation on AA and Anisotropic Filtering.

yep^^^^^^^^^^^^^

Anti-aliasing removes the jaggies from an image by bluring the pixels of the image.


Antistropic filtering makes the texture quality much higher by rendering the further away images with higher percision.

Think the boys summed it up nicely.

Anyone know how much nicer Adaptive AA & HQAF make a game look?

 

[Jimi]

Adaptive AA just smooths out the jaggies on vegatation and fences.

Here's and article on Adaptive AA. Not sure about HQAF though, is that for ATI?

Thanks guys
How do you recon doom3 will perform on ultra quality/1600x1200 with max everything !?
I have 7800GT @ 479/1.12 and x2 3800+ @ 2.5ghz with 1gb 416mhz pc3200 ram

doesn't doom 3 require 512mb for ultra mode, like quake 4?

Yeh it does, but i think Q4 is a bit more intense

Yup, box pops up that 512MB videocard is required. Has Doom3 been updated to support 16:10 1680x1050 resolution? Quake 4 has those two settings.
