Mouse and keyboard delay in Windows 10 Edition

Ever since the update around December 10th, Windows 10 edition has been unplayable for me. Something was changed about the smoothness of the movement in-game, and I immediately noticed that when I would swivel my mouse around, it would take significantly longer for the camera to catch up. I've tried enabling and disabling Vsync, uninstalling and reinstalling the game, messing with the sensitivity, waiting for new updates, yet nothing has changed, and the input delay remains to be so severe that I can't play the game. None of the movements I make happen in real time, and it makes the game and my worlds much more difficult to navigate. Please help.
