I posted this in the "Release Discussion", as well. I figured I'd create it's own post as well to see if anyone else has had this issue.
"Before today's driver update (12/11) the tracking with my Touch controllers was smooth. But after the update (V12), the controllers/virtual hands are now "jittery" when moving them around. As if they skip a beat, per se. This issue did happen before the update when I had tried the Beta Channel. When I saw this happening, I switched back to non-beta and, again, everything was smooth. But since now it's was officially released; I can't downgrade the driver to have smooth tracking again. None too pleased about that. (I tried a repair, but to no avail)"
