I've been having a problem with anti-aliasing in game. When turned on every object will get white dots around the edges, it seems to be most obvious if the object is moving (e.g. asteroids rotating).

Specs are as follows

Core 2 e6600, 2 8800GT in SLI, 4GB of RAM running on Vista 64 bit Ultimate.

I've tried turning off SLI, forcing anti-aliasing through the drivers using both enhance and override in-game settings, upgrading/downgrading drivers, even got these problems when I was running Windows XP.

Any help that can be offered is greatly appreciated.
