Hey, all! As the title states, my maxed out 2016 MBP gets pretty laggy when connected to dual 4k's at 60hz, primarily when resizing or moving windows, and especially when I activate Mission Control. I also do a lot of screen clips through Evernote, and dragging the selector is painfully slow. Monitors are connected on the Caps Lock side of the computer via two DisplayPort adapters. Is this just what I get for not getting a 15" with discrete graphics? Thanks in advance!
