Perimeter

The new technology boasts a nearly maximum efficiency in this highly demanding game. Perimeter has always favored ATI’s GPUs, but now they cannot compete with the tremendous power of the two NV45 processors.

It’s the same in the “eye candy” mode with enabled full-screen antialiasing and anisotropic filtering, but the GeForce 6600 GT SLI pair once again is limited by the amount of the graphics memory. Besides that, two 128-bit busses do not equal one 256-bit bus: their total efficiency will surely be lower for the same very reason for which two SLI graphics cards are not exactly two times faster than a single card.
