Please excuse double post but here is a better sky, I only altered 1 option within my control panel for the graphics card:
Enable Geometry instancing = checked (not sure if that was responsible but everything else stayed the same before I posted this thread
These are the Catalyst 7.3's don't think they have been out for long, was using much older drivers before, but that was a case of having too as other problems arose using the 7.2's
Thanks for your help GakunGak
