Magnificent as always K2.
Just a query, in the image below (with 3D clouds switched off, my system can't handle them

) the cloud layer seems to be duplicated 3 times and off-set slightly. This is also the case in the Stock game and so is not your fault. Is this just a trick to simulate depth with two 2-dimensional images or just to have the layers move over one another to simulate a swirling atmosphere? Most importantly, would removing the extra layers improve frame rates?
