Tried 8.0 M2 drivers today, still lagging, support tool output attached (EDIT: later removed).
I reproduced it with all external USB devices disconnected, only external display (in the Replace display mode - Show only on 2) and Ethernet cable connected to the dock.
Restarted Windows, logged in, moved around with the cursor (using the builtin touchpad) - the occasional lag was there (cursor stuttering on the display). Similar lag also visible when typing on the keyboard.
Back to 7.9 M7 with no lag.
