Extreme lag in Essentials 5 OS X 10.11 El Capitan

My apologies in advance if this has been covered already, I searched and did not find anything.  I just installed Essentials 5 on an Early 2015 Macbook Pro 13" model running OS X 10.11 El Capitan and I am using the Wacom Intuos Art model tablet.  I am getting extreme lag with every single stroke.  It's so bad that I can make a few quick strokes, take the pen away and literally watch the strokes draw themselves on the canvas.  I'm not exactly sure whats going on because Photoshop and Mischief work fine.  Any ideas?  Thanks
