Today Adobe updated all its CC apps to the new 2015 version. Since Adobe said it would support Metal I wondered someone did some benchmark or has general performance impressions? Currently, Photoshop CC 2015 is still very laggy and never feels snappy, especially moving layers still feels like moving tectonic plates. (1st gen rMBP 15, Yosemite). The days PS ate all your RAM and 40Gigs of scratch disk seems over, but overall it still remains a slow app. I really hope Metal can change this.
