Same issue with a mobile Nvidia 1060 with updated drivers. Driver release date is Dec 9 2020, 3 days ago. I am also experiencing the same input lag TheProGamer mentions, even in the menus. Delay is around 100-200ms. I am not getting the delay in Java edition, and have not had it on Bedrock in the past.
Turning down the graphics settings did not help.
I've attached a 60fps video showing the input lag in the menu. By my count, the play button was highlighted 5 frames (83ms) after the mouse was visible over the button. I believe the in-game delay was worse but don't have an easy way to test it. Fighting & building in creative feels very sluggish. Switching back to Java Edition until this resolves.
EDIT: Not sure if it's relevant, but I'm also experiencing MCPE-107479 (outdated driver warning) despite having a 3 day old Nvidia driver for my 1060.
