This game is equally unfriendly towards both SLI and CrossFire: it runs slower when you turn on the multi-GPU rendering mode – almost two times slower on the CrossFire platform.

When you turn on SLI AA or Super AA on a multi-GPU system, you do not take some load off the main graphics card because the second card only performs additional full-screen antialiasing for a higher overall image quality. Neither CrossFire nor SLI has any problems here. As for their speeds, ATI’s solution is faster in the same way as the single RADEON X1800 XT is faster than the single GeForce 7800 GTX.

The gap between the competing multi-GPU platforms gets wider as we approach the most extreme FSAA modes and the RADEON X1800 XT CrossFire provides a comfortable frame rate in all resolutions even though it delivers a somewhat worse image quality – the performance of this platform doesn’t lower as much as that of the GeForce 7800 GTX SLI.
