  • Pixel Shader 2.0.   DirectX 9.0 exposes true programmability of the pixel shading engine.  This makes procedural shading on a GPU possible for the first time.
     
  • Vertex Shader 2.0.  DirectX 9.0 dramatically enhances the power of the previous DirectX vertex shader by increasing the length and flexibility of vertex programs.
     
  • High-precision, floating-point color.  DirectX 9.0 breaks the mathematical precision barrier that has limited PC graphics in the past.  Precision, and therefore visual quality, is increased with 128-bit floating-point color per pixel.
