I've been buying and using the Adobe Creative programs for over 25 years and they have never run as poorly as they do since the new CC rental model. I use Photoshop, Illustrator, and InDesign daily. They all take forever to load and while working within the programs, they temporarily freeze and stutter frequently. I am operating on a late 2015 iMac with 16GB of memory, 3.2 GHz Intel Core i5, and with the latest Mac OS Sierra / Version 10.12.3 — So my system should not be the issue, as I don't have any of these issues within non-CC related programs. Reading elsewhere that these are common issues with the new CC product line. Can we expect upgrades with fixes soon?
What have you done for trouble-shooting and performance-improving so far? (see below links)
