+### Cleanup pipeline texture memory **New in V2.4!**
+Handling minimal amounts of GPU memory is handled internally, but a good practice is to clean up memory you no longer need.
+Cleanup kernel outputs by using `texture.delete()` to keep GPU memory as small as possible.
+
+NOTE: Internally textures will only release from memory if there are no references to them,
