Hi there, can anyone shed some light on the speed of the nMP in Sierra. I am talking about general smoothness specifically photoshop. I have a new MacBook Pro 13inch on a 4K display and it jerk and stutters when panning, also in the OS even things like youtube when you click fullscreen, it doesn't scale smoothly its takes 3 bites to go from windowed to full screen but the playback is smooth, its driving me crazy! I need to get a machine to run a virtual machine, a image rip server and the still handle my normal image editing work. I can't handle the choppiness of the current MacBook Pro 2016 touch, I had a 2015 15inch and it was great. Whats with apple these days? Anyway back to the topic, please any feedback on performance with 4K screens in daily tasks, not rendering and suchlike would be appreciated. Thanks.
