NFS Undercover DX9 editing shaders

Hello. Need your help)

  1. How do I edit shaders in DX9 games? When running Special K, the game has a list of shaders available, and you can change them, but how do I save the shader settings so that everyone does not go to the menu and fix everything again when starting the game :frowning:
  2. Is there an easy way to save shader settings?
    Thank you all very much)
