I've been using my 4870HD for over half a year now, always on max quality in Ati CCC (8xAA and 16xAF). Without a change in software, hardware or (driver) settings I suddenly have quite some jaggies with 8xaa and 16xaf. Thought I accidently switched a setting, but couldn't find anything wrong. A few days ago it was all fine, and now without a reason some settings don't seem to have effect anymore. I switched back to default settings and put everything back manually to my likings (max, hehe) but nothing changed. I uninstalled the display driver + Ati CCC, used both driver cleaner pro and driver sweeper, downloaded and installed DD + CCC again, but it's still not what is used to be.. Next thing that came up in my mind was to try Ati Tray Tools, but it didn't change anything. I also downloaded the latest directx again but this didn't work too. I'm using CCC 9.2, and didn't had any issues with it until yesterday. Does anyone has an idea what's going on? Ps; it's not that the AA and AF are disabled completely, if I do that it looks way worse. It's just that the max settings don't seem to be max anymore. I mainly play racing sims, and it's the same in every sim. I hope someone can help me out.
