Comanche 4 is a helicopter simulation using the DirectX 8.1 graphics interface. It is used to test the memory and 3D subsystems of a motherboard and video processor. Any weaknesses will show up through this intensive benchmark.
I went ahead and ran multiple resolutions once again to ensure a complete picture. While the results show similar FPS rates between the different screen sizes, the results were nearly the same throughout testing. All FPS rates resulted in a 3-4% higher rating for the nForce2 board.
