3.7.2 Render Window

Closing the render window will also speed up things. If your render is writing a lot of text to the message window, either hiding it (select an editor window for example), or better still, minimizing POV-Ray for Windows, will help somewhat. Note that the effect that these actions have is generally directly related to the time it takes to render the file, and the resolution of the render. They have less effect on long renders, and more effect on very fast renders.
