I've gone back to ATI for the first time since my 9700 Pro and I'm slightly confused by one of the Catalyst settings. I'm replaying HL2 and I've set "let application choose AA settings" in the driver and set 4x MSAA in-game. However, there's a setting in the driver to choose the type of AA, with MSAA being the lowest, whereas I've set it to the highest, supersampling. There's no option for this to choose whether it's controlled by the app or drive, so which is the game using?
 
To clarify, it's not the level of AA (2x, 4x, 8x etc) applied I'm confused about, it's the type - multi or super?
 
Multi-sample is the standard way. It's what games when AA is supported. Adaptive AA will add to this by working on transparent and alpha textures. Super-sampling is a brute force approach. It renders the scene either 2,4 or 8 times the resolution of your screen, and then down-sample to your monitor's native resolution. It results in a better image, but it requires a shit-load of work. It's only for older DX9 games and it can make textures a bit blurry. You can fix that by using ATI tray Tools and set the LOD to -2.
