I never used TiR with a monitor since I tried VR. The scale, depth perception, situational awareness, it's just a no-brainer in my opinion.
Also, I was really annoyed by the fact TiR is twitchy as hell, often not doing what I wanted it to do, suddenly flipping the view when looking a certain way, etc.
No, never going back. I'm just going to keep upgrading for VR only. :)
