Far Cry

Far Cry is a title that awards the use of multiple GPUs, as the benchmarks are evidence to. With AA 4x and anisotropic filtering set at 16x with the resolution at 2048x1560 pixels, the significant workload on the Quad SLI setup does not allow the Quad SLI configuration to keep a major advantage over the two ATI Crossfire systems.

The picture changes here when AA 8x is enabled: the GeForce 7950 GX2 Quad SLI Solution distances itself in terms of performance from the two Crossfire solutions. The benchmarks also present a much more interesting topic on the analysis of performance scalability. Once more, we see strong performance displayed by the GeForce 7950 GX2 and see very little performance lost when passing from 4xAA to 8xAA.
