I'm not really sure if the performance problem is entirel apple's fault. I think it might be hardware issue. I've watched quite a few presentations of your products on youtube and the playback was pretty smooth (esp. Dell D3100 which streams in 4k, so that had to be smooth). In general my feeling is that external screen connected through the dongle is not really keeping up 60Hz.
I still wonder if on that Dell docking station it would be any better.
