Everyone knows the retina display is a gorgeous display and it is a big step up compared to the non-retina ones. I have been using many different MacBook Pro models over the past few months and I am currently working on a Late 2013 retina MacBook Pro 13, although the El Capitan fixed most of lag I had with Yosemite it still feels laggy sometimes. I use a lot of Photoshop and it performs better when I use my MBP plugged in an 1080p external monitor, on the retina display it feels choppy. Also see it happening with many different apps and websites like Google Maps. They work perfectly on a non-retina display, but when I switch back to retina it gets choppy again and it annoys me a lot. Is the retina display support something not quite stable yet? Should I change to a non-retina display MacBook like an Air or I better be patience until it gets fixed? Sometimes I have the impression that the retina display is a "beta" product and for now we should stick to the non-retina ones for serious work.
