Tried out the VR last night and wow is it good. I played with Smooth turning on and a low level setting for "blinders". The game offers a good handful of comfort options. Normally I have my camera up on the TV pointed down, but moved it under the TV which got rid of the blue grid/cage area. As for using the DualShock 4, it's working really well, and much better than I expected.
The physics are even more ridiculous in this mode and it's great. You can push peoples heads around, choke them out and toss their body around, move their body around with objects, etc. The animation 47 does with his hands when you're about to choke someone out is so menacing and dumb, but at the same time perfect. Just simply walking up and punching people is super fun
Guns work surprisingly well and are lots of fun to use, aiming down sights works or you can simply hipfire. Everything happening in first person is just that much better and funny moments are frequent. Getting caught dragging a body and looking up at the guard in surprise, punching the wrong person, etc.
Graphically it's obviously not as good, but for VR and of this scale and with all the details is really good. The biggest thing is far away NPC/crowd pop-in in the more dense areas. Even with the lower graphics the sense of scale and immersion is insane and I've only done Dubai so far. Cannot wait to play more levels!
Is it perfect? No, but it's ridiculously fun and I highly recommend it to anyone who has PSVR or was thinking about getting the headset. Only negative for me is that I have to have a PS5 copy and PS4 copy installed at once to go between them, but for Hitman it's worth it.
