There is more debris and grass around levels to add detail to terrain. These shadows are created by generating cube maps on the fly from each light source and using a combination of instancing and geometry shading to create the effect. All lights can cast shadows, making night scenes more detailed than on the DX9 version. The lighting model has been upgraded to be completely per pixel with softer and more shadows.

Let's take a look at some of what has been added in with the DX10 version. That's not to say that DX10 exclusive features aren't there (they do make use of geometry shaders in new effects) it's just that doing things in a way similar to how they are currently done offers better performance and consistency between hardware platforms. In the end, a lot of the DX10 specific features included in CoH had to be rewritten in a way that could have been implemented on DX9 as well. This certainly made it hard for early adopters to produce workable code before the arrival of hardware, as developers had no idea which features would run fastest and most efficiently. In spite of the fact that Microsoft requires support for specific features in order to be certified as a DX10 part, requiring a minimum level of performance for features is not part of the deal.

Apparently Relic was very aggressive in their use of DX10 specific features and had to scale back their effort to better fit the actual hardware that ended up hitting the street. We are told that it's quite difficult to develop a game when going only by the specifications of the API. While Company of Heroes was first out of the gate with a DirectX 10 version, Relic didn't simply recompile their DX9 code for DX10 Company of Heroes was planned for DX10 from the start before there was any hardware available to test with.
