r_fastsky

With r_fastsky you can switch between the detailed skybox to be drawn or just a basic sky.

Usage:
/seta r_fastsky 1
then do:
/vid_restart

Values: “0” or “1”

Note:
With r_fastsky 1 the sky will be filled with some sort of black. Basically there will be no texture so your hardware don’t have to render the texture.
