Don't be discouraged heruca. No one ever learned to fly before they could walk, and its the same with software development I'm sure.

I use CC3 mainly, and apart from the speed issue you tend to get when you have a map with 135 sheets (those are layers in PS-speak), and 350 sheet effects (layer effects), then things are going to be just a tad on the slow side - even with a 64-bit app I have yet to see a bitmap app that can handle that many layers in one doc, and throw out renders (exports) at 10,000 pi square - but CC3 seems to do it ok, even though its only a 32-bit app
