Yeah, it's a good first step but feels too sluggish to be useful. Hopefully PD will do some tuning now that they've finally given in and implemented it.
It is pretty rough. The only workaround I've found is that pushing the stick down (R3) gives you an instant look behind but my muscle memory was still flicking the stick so I've had to unassign that on the controller mapping. Hopefully it is refined in the next update.
Right stick is to look around and back, and you can map a different key to just look behind like it used to be, without the rotation. Takes some time to get used to the change but its good to have. I use L1 for look back button
