Far Cry
Single GPU

The Chrome S27 is marginally quicker than the 6600 DDR2 and then the X1300 in our Far Cry test, with all cards posting similar results with no AA or AF applied.
MultiChrome, SLI and Crossfire

When asked to scale with another board in multi-GPU mode, SLI and Crossfire enable NVIDIA's and ATI's hardware to overtake MultiChrome S27s, S3's driver not doing as much to help -- especially at 1024x768 -- versus the single board results. 30% extra performance was to be had at 1280x1024, though.
