Benchmark Results: 4x AA
The StarCraft II beta doesn't include an anti-aliasing (AA) setting at this time, and it's unclear at this point if the released version will offer that functionality. In the meantime, we tried forcing AA through the Radeon and GeForce driver panels. The feature didn't seem to work on the Radeon cards, but all of the GeForce cards we tested except the GeForce 9600 GT were able to handle AA successfully. Here are the results:
The GeForce 9800 GT seems to have trouble running the game at 2560x1600, probably due to its smaller 512MB frame buffer. Otherwise, the GeForce GTS 250 is on the verge of playable at 1280x1024, and only the GeForce GTX 260 is able to offer playable performance up to 1680x1050. Hopefully, the developers will include a performance-friendly AA option in the game by the time it goes live.
