Star Wars Knights of the Old Republic II: The Sith Lords

What video options in the game are affected by Vertex Shader and Pixel Shader (VS/PS) graphics card effects?

When playing Star Wars Knights of the Old Republic II: The Sith Lords on a graphics card without Vertex Shader and Pixel Shader (VS/PS) capabilities, you will be unable to adjust the Soft Shadows and Frame Buffer Effects options because these options are not supported when Vertex Shader and Pixel Shaders are not available.
