If you edit "...\steamapps\common\Divinity II - Dragon Knight Saga\data\globalswitches.xml":
render_framerate="1"
then you can display in the upper left your current FPS for the 3 engines as explained here:
White: The frequency of screen updates (i.e. what is usually called frame rate)
Red: The frequency of updates of the gameworld simulation
Green: The frequency of updates of the physics simulation

For me ATM (Sept. 2017, Steam version) it says:
W: 75
R: 46
G: 50
and not 75, 75, 75 unfortunately, which is quite strange for this system:
Gaming laptop ASUS G751JY [Intel HM87 Lynx Point, i7-4860HQ, 24GB DDR3L 2133MHz, GTX 980M (GM204M, 10DE-1617/1043-22DA Rev A1, vBIOS v84.04.48.00.39), 4GB GDDR5 (Micron), G-Sync], Windows 10 x64, display: LG Philips LP173WF4-SPD1 (LGD046C) 17", desktop res: 1080p 75Hz, Audio: Realtek

It looks like an engine issue not correctly scaling (75,75,75) on some modern HW...
