Huh, I still have that line in my RadeonPro xml files for any profile I do for a game. Wonder why it isn't showing up in yours?
I just checked my profile for Mass Effect I have in Radeon Pro and the Catalyst AI entry is still there. The individual game profiles are located under your user name, in the
AppData/Roamin/RadeonPro/Profiles directory. I don't have anything special toggled in RadeonPro to access additonal settings.
No way to ask about it either since it is no longer updated.
However, since that test was run on the 8.93 drivers, the newer 8.95 or 8.96 may let you force the AA using the Override Application setting now.
I also don't have any of the Catalyst Application Profiles (CAPS) installed either.
Maybe with the new(er) drivers you can override the AA in more games. Used to be a real pain if the game used deferred rendering. I'll have to try Need for Speed Hot Pursuit and see if I can override it there (before I had to use a 10.10e custom driver profile).
Also, I was running a 6950 (unlocked to 6970) at the time, and am now running a 7950. I'm pretty sure the AF filtering is different in the high end 6000 series and was again revamped in the high end 7900 series. It could very well be the architecture differences that show the change when I force the AF.
I haven't played Skryim in a month (decided to actually finish Mass Effect 2 and am know doing ME3... gahk, talk about graphic tweaking to get a nice picture). Someday I'm going to get back to it and finish the main quest
