Company of Heroes
We don’t use the eye candy mode in this game due to its having problems with FSAA. We test it with anisotropic filtering only. The version 1.70 patch adds DirectX 10 support, so we ran the game in two modes, DirectX 9 and DirectX 10.
The CrossFire platform is victorious once again. Like in the previous test, this is true for both versions of Radeon HD 2900 XT in the tandem. It’s only in 2560x1600 that the single Radeon HD 2900 XT with the faster GDDR4 memory is about 5% ahead of the junior model. This is one of the most successful tests (another one is the 2048x1536 resolution in Battlefield 2142) for the new graphics card. Note that the Radeon HD 2900 XT 1GB CrossFire platform and the GeForce 8800 Ultra offer a comparable reserve of speed at a resolution of 2560x1600 pixels.
We can’t say DirectX 10 makes the game much more attractive. Company of Heroes was originally developed within the DirectX 9 framework after all. However, the lighting of the scene looks better in this mode. Shadows are softer and more realistic, and smaller details look better due to the new special effects. The shader-based grass, which is missing in the DirectX 9 mode, looks particularly good. The physical model is improved in the DirectX 10 mode, too.
The tradeoff for this is a terrible performance hit in the DirectX 10 mode: the Radeon HD 2900 XT 1GB CrossFire tandem can hardly yield 27fps with slowdowns to 12fps in 1600x1200! The GeForce 8800 Ultra isn’t any better: only 30fps with slowdowns to 10fps. The less advanced DirectX 10-compatible solutions look even more depressing. Of course, there’s no talking about normal play in the DirectX 10 mode: the improvements in the image quality area are not so deep as to justify the terrible loss of speed.
