Scale shaders

[RekZ]

I would like to know if there is a way to scale the world shaders within the game, without the need to create different versions for different resolutions.

For example, I have the shader images at a resolution of 512x512, and I would like to reduce the resolution IN-GAME to 128x128. I know that the 'DxCreateTexture' function creates mipmaps for textures, but I'm not sure if that could be used to benefit my case.
