Well I have a HD 4870 ATI card with the newest driver updates, but for some reason AA just doesn't want to work in games. If I turn AA all the way up, it just makes it worse so I have to reset everything to the factory defaults.
I'm kinda hoping someone else has this problem or heard of it...
AMD 64 X2 Dual
Core Processor 5200+
4 Gigs RAM
Windows XP Home
I havent played that game spo I cant tell you for sure, but it might be using a lot of transparency textures, in that case you need to use different AA. Try switching the AA in CCC from boxed, to Edge detect and see if you notice any differences.
Also note that some games just cant be aliased no matter what card you are using.
Ex. GTA IV, S.T.A.L.K.E.R....
Try uninstalling you r dirvers and then installing the latest Cat 9.4 drivers.
I've never experienced nor heard anyone having problems with AA.
If you have Riva Tunner installed, uninstall that app since it supersedes the CCC settings.
One thing is for sure it has to be a software related issue.
I'm having the same problem with a Gigabyte 4670. I have been playing battlefied 2 and Warhammer 40000 with no issues for about 6 months now. With no changes made all of a sudden my AA seems to have quit. I've looked all over, but no joy. I reinstalled my games first, no change. I removed my video card from device mangler, and installed the newest catalyst from the ATI website, no change. I then used Burnintest and Furmark while monitoring my power voltages, and all tests fine. Used some memory testing software for the video card, all passes. AA does not work with any settings changes.
Another curious thing, when I fly over land in BF2, I get dancing black circles on the ground in front of me. <Scratch head>
Edit: Could someone with a 4870 post a screenshot of a game they play that supports AA, and have the AA cranked all the way up? Maybe a screenshot with Application Controlled AA then another with forced AA.
