|To give you sim fans a small taste of what these cards can do, we used Novalogic's combat helicopter simulator Comanche 4 for our next batch of DirectX tests. Comanche 4 uses DX8 class pixel and vertex shaders to produce some of the realistic visuals used throughout the game. Unlike some of the previous tests though, this benchmark is heavily influenced by CPU and system memory performance, especially at lower resolutions. However, when the resolution is raised and anti-aliasing and anisotropic filtering are enabled, the current crop of 3D accelerators tend to slow down quite a bit.|
With the exception of the Radeon 9800 XT when anti-aliasing and Anisotropic filtering were enabled concurrently, all of the cards we tested were basically CPU limited in the 1024x768, so we'll focus on the frame-rates at 1600x1200. At this higher-resolution, the GeForce 6800 once again outran the 5950 Ultra and 9800 XT at every configuration. The GT and X800 Pro were too much for the 12-Pipe 6800 to handle, but that's to be expected considering they're clocked much higher and cost substantially more then the 6800.
