The app uses "pure" DirectX 9, unlike the previous version, and the floating-point-enabled Shader Model 2.0 is now a baseline. 3DMark05 dynamically generates shader code in Microsoft's High Level Shader Language and supports a broad range of shader compile targets, so it can take best advantage of the Radeon X700/X800 series via Shader Model 2.0b and the GeForce 6 series via Shader Model 3.0.
