Even the slightly optimized adaptive antialiasing on the Radeon X1900 XTX won't do much in this game. It's simply too heavy for current cards to run with 4x supersampling transparency antialiasing. You'll have to drop to 2x (or 2xQ on the GeForce 7 series) if you want the best compromise between image quality and playable frame rates. There's is one interesting fact here. It appears that the Radeon X1900 XTX is doing some additional work with multisampling than just standard 4x AA and 16x AF. Interesting, but not really useful since there's still very visible aliasing. We won't display the 2x results here, because they're pretty much the same (although nominally they are higher).

With supersampling, neither card can offer sustained frame rate over the minimum 30 fps mark all the way through the replay / demo. They're pretty much bunched up below 30 fps. You have to use 2x antialiasing if you want higher frame rates. Even then, you frame rate will still occasionally drop to below 30 fps at one time or another. This game proves that transparency antialiasing is only applicable to older games. Next, we move HDR test results.
