Just tried it for the first time in VR, no problems regarding FPS.
Just discovered how I suck at CASE I landings, although I messed most of them up because of fiddling with the comms, since the VAICOM PRO Realistic ATC isn't released yet and I can't just talk to ATC. :P
Other than that, freaking great! Much more immersive, the crew, the comms, the works. Now I can't wait for crew & ATC comms on airfields.
