There is a pretty sharp decline in smoothness of panning, zooming, dragging elements around the screen in Ai CS6.
Using both versions side by side on MacBook Pro i7, 8gb Ram, 10.6.8. Ai v16.0.0. The files are as small as 0-200k.
Ai CS6 is simply jumpy and laggy. Try a new blank artboard of 800x600 in both and drag around view at 100% zoom. The artboard skips around.
It's not unusable, but its there, and for me overshadows the improvements.
Thanks,
Brent
