Exact same issue for me (XPS 9360, Ubuntu 16.04, did an apt upgrade and performance is now terrible).

glxgears is running at 1Hz (unless a part of the window is on the native screen). All the suggested hacks (adding options to /usr/share/X11/xorg.conf.d/20-intel.conf) do not work (I'm not sure how to check whether they are even applied).

My system was working fine and is now barely usable. Can you provide a fix or at least instructions to downgrade? Booting 4.4.0-72 kernel is yielding the same result, as stated by hinchliff.
