A shader defines the material of and is attached to a 3D object. Uboats use metal shaders, a crewman's face uses a skin shader, and so forth. Shaders can be implemented in many ways. Two of the most common are vertex shaders and pixel shaders.

Pixel shaders ultimately boil down to answering the question, "given the locations of lights and objects in this scene, what colour should this pixel be?" This question is well suited to massive parallelism and all current model video cards accordingly have hardware pixel shader support. Pixel shaders are well suited to simulating multi-layer surface properties such as water.

The Geforce 6200 supports Microsoft's DirectX 9.0 Shader Model 3.0 (including Pixel Shader Model 3.0). However, it is an older card (it was introduced toward the end of 2004) and has only 4 pixel shader processors. By way of contrast, the 6800GT has 16 pixel shader processors, the 7800GT has 20 and the 7900GT has 24.
