Open Catalyst control center and go to "3D" section,choose "AA" tab and make sure "Use application settings" is checked.
I have always had it set to use application settings. In fact, I don't let CCC control any of those settings.
Also does it give you any errors when it freezes ?
Well, when I have error reporting on in CCC, it asks me to send a report to ATI, but then it wants to send it with outlook instead of via the error reporting app (lol).
All I know is that if AA is on in any way, the card will stop responding and take about a minute to reset.
Even recently, I don't even have to be playing a game or doing anything GPU intensive. Four times this week the card stopped responding while browsing the internet. Is my card dying now?
