Unfortunately, nope. As I mentionned earlier, on this thread or another adobe illustrator thread for the same issues, the smaller the screen resolution is, the faster Illustrator is running. On the 27" Ultrafine 5K, the Outline view is almost unusable and the GPU preview is getting so slow as the document gets more loaded with basic shapes and small effects. However working On the Cintiq 16 Pro (smaller with less pixels displayed) the soft runs faster on Outline and on GPU preview. By dragging the Illustrator window from Cintiq display to 5k display, everything goes slow again. Again my setup : Hardware : MBP 15" w/ touch bar 2016 (I7 2,9, 16 Gb Radeon 460 4Gb 1Tb) Software : Mac OS Sierra 10.12.6 public beta 2 / Illustrator 21.1 Monitors : Ultrafine 5K & Cintiq PRO 16"
