# Avoid Buffer Clearing

Clear only buffers that need to be cleared.

<div class="contents" id="bkmrk-color-buffer%3A-the-co"><div class="textblock">- Color buffer: The color buffer does not have to be cleared if the scene is known to cover all of it.   
    For instance, this is the case if the background image or a sky map covers the whole surface.
- Stencil buffer: Only needs to be cleared if it is actually used.
- Depth buffer: If depth test is enabled.
