Race Driver: GRID replaces DiRT for our GPU motorsport benchmark test. We recorded frame rates with FRAPS in this fantastic looking game as we took a Camaro for one lap around the San Francisco Pro muscle track. Anti-aliasing was enabled via the game and anisotropic filtering through the driver control panel.
GRID scales somewhat at the lower resolutions, which is understandable since the GPU load is less with such settings. As the resolution is increased, however, each multi-GPU solution pulls ahead by 40% at 2560×1600, though the larger frame buffer of the X2 again produces no real advantage over the regular 4870s.
Silent Hunter: Wolves of the Pacific was tested during an attack on a convoy. All in-game settings were enabled and placed at their highest options.
Wolves of the Pacific, like IL-2: 1946, shows no real performance gains with a second GPU installed, though the game’s frame rate drops consistently with higher resolutions.
World in Conflict ships with a benchmark test included, which we used under the high preset with 4x AA and 16x AF then enabled in-game. DX10 was enabled in the advanced graphics options.
This fantastic looking RTS scales quite well with the additional GPUs of the X2 and two 4870s, though it displayed no significant variance between the two multi-GPU solutions. Even as low as 1280×1024 the single 4870 was outperformed a solid 15%, and that gap increased to 20%, 30% and 80% at the higher resolutions, respectively.
