When using a Dualshock 4 for this game, the touchpad in its centre can be used to turn the camera horizontally. Maybe there's a handy way of utilising this function (like looking around quickly?) but I haven't figured that out yet. Instead, my thumbs keep touching its corners accidentally, causing the camera to "bug" around (not an actual bug, just looks like it).
It really messes with my orientation so it would be cool if there was an option to unbind the touchpad.
