Just got Oculus Rift the other day, and boy it's super immersive. Though I went against my better judgement and built an SLI PC, only to found out the hard way that Oculus Rift doesn't work with SLI, so I had to disable the second card to run DCS:mad:
In anycase, I found it super fun to poke my head out out of the window, occasionally even standing up to look behind me. Although, when in cockpit there's quite a bit of cognitive dissonance looking down because my sticks and petals are in the same place as they are in the plane.
