Adaptive Anti-Aliasing - Radeon X800XL?

Hi all,

Just dl'd and installed Cat 6.5. I have a Radeon X800XL 256Mb (AGP) card. I've read a little about Adaptive AA but so far only on ATI's own literature so wanted to get a bit of independant feedback from other end users...

I gather that it's generally a good thing. My questions are tho, how will it affect performance? Do I need to be forcing AA on in the Catalyst Control Center for it to work or will it still kick in if I leave AA up to the application so long as the Adaptive AA setting is switched on? Are there any "funnies" with it, i.e. only works above/below a certain resolution and/or framerate/refresh rate? Am I likely to really notice much of a difference?

TIA

Not being harsh but the best thing to do is to turn it on and see what it actually does and looks like for you. All computers have different specs so its hard to tell what will happen individually.

Personally I just turn it on and leave it at that. I have never really worked out if it doesn't do any good or not. My opinion is that I just turn things up until it gets unplayable then go back as step and that'll do.

right i leave it on via cat control, and what adaptive aa does, is this >>

as you can see there is a clear difference. (well not after the size has been shrunk via imageshack) but basically the fence dosnt get distorted with adaptive aa on

if i was going to tell the truth, i took these with a 7800gt with the top picture having Super sampling of and the one under neath super sampling AA on.

ATI's adaptive aa will do the same trick though.

as far as i can see performance isnt hit either (much)
