The time cost of signalling and unit computation is fundamentally physical. Drift and error in inertial and position sensing is fundamentally physical.
You can make very good goggles if the money and time per unit isn't an issue. Registration to the point that there are no detectable flaws is very hard. You have a hard timing constraint from the human visual system on the order of 5 to 50 milliseconds. In that time, you need to sense the visual environment, determine position and its derivative vectors, figure out how your simulation needs to be updated, render the new data, and display it to the user.
Not something you can necessarily solve by throwing money and engineering hours at it until it works. In fact, there may be a few Nobel prizes in physics between here and there, or possibly biological integration well beyond our current horizon.
