You have delay in both dragging and hovering and your tablet stops working, mine while dragging is smooth like the mouse even with the 15-1 drivers was like that and never stopped working, so in dragging there was no problems before or now, if you have delay while dragging then your problem must be something else, the real problem was only when hovering, you could notice the delay with the driver 15-1 by a lot, with the 15-2 the delay for me was gone and 15-3 didn't notice anything same like the 15-2, with the hover distance i never had a problem, but i have seen people complain about this, it must be because they were used to the 480, unless someone can prove the delay in a decent way i don't think there is a real answer.
