 ## Advanced Settings ##
 
 * __Camera Material__ - A material applied to the camera output, allows shaders to modify the image. The camera output is set as the `_MainTex` of the material.
-* __Aspect Stretch__ - Apply a stretch to the output, allowing the display to be non square pixels.
-* __Perspective Z__ - Only for perspective cameras. The Z distance from the camera that is rendered as pixel perfect.
+* __Aspect Stretch__ - Apply a stretch to the output, allows the display to be non square pixels.
+* __Down Sample__ - Scales down the render resolution, making the output blockier.
+* __Perspective Z__ - Only for perspective cameras. The Z distance between the near and far clip planes, that is rendered as pixel perfect.
