I have a ASUS ROG Strix GL702ZC laptop that comes with Windows 10 and a Precision Touchpad.
While using the touchpad I find that the two-finger smoothing is very smooth, but it comes with inertia that keeps scrolling a page shortly after you remove your fingers from the touchpad instead of stopping immediately, which is most likely a part of the smooth scrolling implementation. It's not a massive annoyance, but I believe it conflicts with some non-UWP applications (especially with games, where they can assume that you have scrolled the wheel like 30 clicks in a second).
I've had a look around in the Settings app but the only settings for scrolling that I've found are to do with enabling scrolling with two fingers, the speed that the page scrolls, and the direction the page scrolls. Other than that, there's nothing in an interface that appears to allow you to disable the inertial scrolling.
It wouldn't surprise me if the feature can't be disabled in the registry or requires custom non-microsoft drivers to disable it; the touchpad isn't an ELAN or Synaptics touchpad or whatever there is available right now, so the drivers for them will most likely not work correctly if at all.
Is there a way to disable this inertial scrolling, or at least change the touchpad's settings from the registry?
Edit: I have noticed that the Precision Touchpad behaves very similarly to a touchscreen. Scrolling with two fingers behaves as if you're swiping the screen, and zooming is done with a pinch gesture; Microsoft Edge does not let you zoom out to less than 100% zoom with the pinch gesture, just like a touchscreen. This most likely means that this inertial scrolling functionality is part of whatever code manages touchscreens in Windows 10.
