Novalogic's Comanche 4
|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.|
At 1,024 x 768, we see how the benchmark is bound by the CPU. Each card, including the 5900XT, performed on relatively the same level as the other. Once we increased the resolution to 1,600 x 1,200, the graphics card's hardware came more into play, although it was not evident until we started increasing the quality in the drivers. The No AA test still had most cards within a few frames of each other, but once we enabled 4X AA, the declines began. As Anisotropic Filtering was introduced, we could see much better how each card coped with the added work. The V9999 had the best turnout with No AA and 4X AA, but as we typically see with NVIDIA cards, the scores decreased heavily with Anisotropic Filtering enabled, with the X800 Pro being least affected. When you compare the two GeForce models, however, the added MHz that comes with the V9999 makes for some nice gains.
