Huh, my experience with the Vive and a good rig (i7, 32gb ram, gtx1080, etc) has been fluid and easy to use. More useful for tweaking props in my levels than "creating" things, but there are serious opportunities (and some good starts) to sane VR user interfaces. Even if they can just nail using twirl gizmos for fine tuning integer inputs would ripple out and be useful in the 3DS Max / After Effects / video editor / whatever VR software of the future.
