So I have been playing through Return to Castle Wolfenstein lately (I like to play though old games every now and then). Okay, so I have all of the settings all that way as high as they can go (obviously), and noticed that some textures still looked really blocky; now I know this is an old game, but it's not that old. So after messing around in-game, and in the CCC I saw that Catalyst A.I. was set to 'Advanced' somehow. I reset it to 'Standard', went back in-game, and the texture were back to normal. So my question is simple: What does Catalyst A.I. do exactly?
