Benchmarks: Supreme Commander
The Visiontek Radeon HD 4870 still does quite well in Supreme Commander, matching the performance of the GeForce GTX 280 at 1920x1200 and 1680x1050.
Enabling 8xAA saw the Radeon HD 4870 slip behind the GeForce GTX 280 by a very small margin at the higher tested resolutions. The Visiontek board was still able to outperform the GeForce GTX 260 at all three tested resolutions however.
