Hi,

Yes retina resolutions are much slower. I am constantly reminded as I have one 4K screen set to 1080p myself.
From our driver point of view this is exactly as the native 4K resolution so we suspect there is something upstream but we have not yet honed in on the problem.

We have seen increased 4K adoption, I'll increase the priority of this. Will have to come after 10.13.4 woes of course.
