Thanks for all the advice hairy_hen! :D I had always planned to optimise the way I did the up-scaling but for now just needed something quick that would allow me to run my colour tests. :)

dark_jedi I don't know how much you plan to mess with G-Forces script but if its any help I found the anti-aliasing section of the script isn't as effective if done after up-scaling but then as this section of the script increases the vertical resolution by 1.5 I guess it would make sense to incorporate it into the up-scaling process.
