Yeah… If you are StarCraft II gamer and having ATI graphics card, here is a beta driver for you. It supports Anti-Aliasing through the ATI Catalyst Control Center for StarCraft II. This beta driver supports ATI Radeon HD 2xxx, 3xxx, 4xxx and 5xxx series graphics card and ATI Radeon Mobility. It also improves performance for Quad ATI CrossFireX for Eyefinity supported configurations.
I updated the display driver to 10.7a beta. But my poor ATI Radeon HD 4870 512MB cannot perform well even with 2x AA enabled. Getting less than 30 fps when turn AA on. I think that I need to upgrade to ATI Radeon HD 5870 in order to enable AA and play it smoothly. Anyway, StarCraft II is great to play even without AA turn on.
