It was better before the switch to wayland/gnome in 17.10. In 17.04 they actually appeared to have fractional scaling working pretty seamlessly in Unity (not sure exactly what they did to accomplish that), but with the most recent version they are back to integer only. That being said, gnome is expected to have factional scaling support under wayland for 3.28, scheduled for, iirc, March.
