I was finding that playing KCD in cinema mode was resulting in some snaggy movement. When I turned left or right, quite jerky, and you could see multiple images of the reticle moving.
I switched off “tracking prediction” in the VorpX settings and that smoothed it right out.
@Ralf: A suggestion – you may want to auto-default that, when the user changes to cinema mode from Full VR mode. Not sure if this works for other games too, but it made a huge difference here.
