I have 5 files of 11.2MB each I want to merge for a panorama.
It takes 1minute in CS6 to complete the process and render a perfect panorama.
In CC, Alignment of Layers is laborious and uses max CPU resources.
"Blending Selected Layers Based On Content", renders CC unresponsive.
Yes, I am running CC 64bit!
So far my experiance has been, that CC has problems using PC resourses.
