download shader model 3.0/pixel shader 3.0 free
Pixel Shading is a method used for rendering advanced graphical features such as bump mapping and shadows. Most modern PC games utilize pixel shaders in conjunction with advanced GPUs (Graphics Processing Units) found on most Nvidia, ATI and certain Intel video cards. Pixel Shaders also directly correspond with Microsoft's DirectX platform.
Shader Models are components used to help render graphics sent from the CPU to the graphic card. The version of shader model your computer can support is based in the combination between your DirectX version and the version your graphics card can support.
