The precision was already there ten years ago it's just not rippled down to affordable products yet. Unfortunately the games industry is a fickle motivator for this technology, for a while haptic joysticks were in favour but now the interest seems to have waned. You need the partnership of both developers and peripheral manufacturers. I'm sure the O.R. will cause a spurt of that.
Many games already support VR. Take all the TrackIR games for instance. Stereo 3D supports been there for ages as well. My first VR headset (VFX-1) had stereo 3D, headtracking, and was supported by games lik EF2000, Commanche 3, Flight Unlimited (1 and 2), Thief, System Shock (1 and 2), Terra Nova, and many others.
O.R. really brings some innovation in the hardware and price. Enabling games support won't be hard.
