This is when you're in VR mode on the PS4:  When you look left to right, the world dips on an angle to either the left or right (depending which way you're looking) in addition to where you look. As you turn from the left or the right back to centre, it dips up to become straight again. It's subtle, but it's there. Tested on both a PS4 Pro and base system - both with different headsets in different rooms. }}{{I'm not tilting my head in real life, but in minecraft, a tilt occurs.  Posted this in Reddit /PSVR as the discussion threads on nausea are being posted.   There should be no world tilt when you're looking left or right.  The world should remain straight and match the movement of your head.  This anomaly does not occur in any other PSVR game, so it is strictly a bug with the PSVR implementation.  Thank you.
