VooDooPC May 25, 2006 Share VooDooPC Member May 25, 2006 Adaptive Anti-Aliasing smoothes out the surfaces in an entire scene unlike Multi-Sample which works only on edge surfaces. Adaptive AA has the ability to work on transparent or opaque texels, like those that comprise a surface texture. Previously this feature was available on the ATI Radeon® X1000 family products. Starting with Catalyst® 6.5, Adaptive AA support is now available to ATI Radeon® 9500 products and above. Has anyone tried this? Does it look much different than normal AA? Is the performance hit greater than AA? Link to comment Share on other sites More sharing options...
Cujo May 25, 2006 Share Cujo Member May 25, 2006 i use adaptive aa all the time in cs:s. makes fences look amazing. not much of a performance hit. in other games like nfs:mw i have to turn it off though. yes the performance hit is much greater then aa. have not played any games with the 6.5s yet but installed them today.

Guest zerodamage May 25, 2006 Share Guest zerodamage Guests May 25, 2006 This has been a possible feature since Winter. ATI held it back due to the initial sales of the X1800 series. Link to comment Share on other sites More sharing options...
VooDooPC May 25, 2006 Author Share VooDooPC Member May 25, 2006 I knew you could enable it in the registry but now that they have officialy added it, they have the option for "Performance" and "Quality", so I assume they had tweaked it a bit.

Vovik May 26, 2006 Share Vovik Member May 26, 2006 Yeah, so I tried it in CSS and my diagnosis is that it eats frames worse than HDR. When I turn everything on max (6x AA, 16x AF, etc) and HDR and Adaptive AA at 1280x1024 i get around 30-40 frames in an empty map with 3 bots (i tried on nuke). As soon as I turn off Adaptive AA I get frames up to 80 but not very stable. Further, when I turn off HDR I get almost no framerate loss, but I know it will decrease with more ppl in real servers.

Cujo May 26, 2006 Share Cujo Member May 26, 2006 ya adaptive aa is really only usable with x1800/x1900 cards and crossfire. my guess would be the only reason ati added this support is for marketing so they can say "hey, these old cards have this feature".
