Benchmarks: Supreme Commander
Supreme Commander favors the Radeon HD 3870 with AA/AF disabled, giving it a comfortable lead over the GeForce 9600 GT. The Radeon HD 3870 is 17% faster at 1920x1200. However, the Crossfire setup is only 10% faster than the SLI GeForce 9600 GT cards.
Building more of a pattern we find that turning anti-aliasing on really hurts the Radeon, while the 8xAA setting had minimal impact on the GeForce 9600 GT. The Radeon was able to remain on top but not by a comfortable enough margin.
