2-way and 3-way AMD CrossFire and NVIDIA SLI scaling on Intel Sandy Bridge
A third-person shooter, Lost Planet 2 is the sequel to Lost Planet: Extreme Condition.

NVIDIA’s GeForce GTX 570 and GTX 580 may obliterate the competition, but they fall behind in multi-GPU scaling. AMD has better scaling with 1.65x and 2x for 2-way and 3-way configurations respectively, compared to 1.6x and 1.7x respectively for NVIDIA.
Bumping up the resolution a notch, 2-way scaling performance is rather similar between both GPU makers at 1.7x. AMD still has the upper hand in 3-way scaling with an improvement of 2.15x to 1.85x though.
Similar to the resolution of 1920 x 1200, 2-way scaling of the four GPUs tested is similar. For 3-way scaling, AMD posts a performance increase of 2.3x and NVIDIA 2.15x.
While CrossFire and SLI can offer gamers the potential to nearly double or triple frame rates, it does not always happen. Lost Planet 2 is one such example, with scaling performance at 1.7x for 2-way configurations, and just 2.3x for 3-way configurations at best. Going from 2-way to 3-way brings about minimal performance benefit regardless of AMD or NVIDIA GPUs.
