The retina display causes any somewhat graphic intensive apps to be laggy. It's a major design flaw. You can fix this by right clicking on any app and clicking "get info". Then click on "open in low resolution". You'll be surprised to see how fast apps run now. It will look not as clear, however. The retina sucks. My 2011 macbook ran everything better ...

So now I have the 2017 MacBook Pro 15" with AMD Radeon RP560. It works with 2 External 4K Displays. It is really slow with the internal Intel Graphics Chipset. But you can deactivate automatic Graphics switching in System Settings -> Energy Saving. Then it is really usable. I tried first with two Belkin Adapters (http://www.belkin.com/de/p/P-F2CU038/) for ...
