SLI Performance: FarCry

 

FarCry is an interesting game and game engine in that although it employs some of the more up-to-date, leading-edge DX9 pixel shader and lighting effects, it's still somewhat CPU-bound, as you'll see in the following tests.  Well, at least when you're driving things with a pair of GeForce 6800 GTs, anyway.

FarCry - With Dual PCIe Graphics
SLI Driven DirectX 9 Gaming Performance With Dual X16 PEG Slots

 

Between 1280 and 1600 res, we see very little variance in performance overall between the two motherboard solutions we tested.  The ASUS A8N32 SLI Deluxe does, however, have a slight advantage consistent with what we saw in our Doom 3 tests, without Anti-Aliasing or Anisotropic Filtering enabled.  Again, this is due largely to the fact that there is more inter-GPU communication going on at these higher frame rates.  With AA and AF turned on, however, the scores are completely leveled. 

Next we'll plug in a pair of GeForce 7800 GTX cards and turn on SLI-AA to see if we can invoke even more GPU-to-GPU traffic over PCI Express, with the blending that is required in this type of AA rendering technique.
