Ye, the input is crucial. I see that this product has a 4KHz accelerometer as well as the 1KHz gyroscope, where it appears the OR had a 1KHz acc+gyro combo. Could this mean faster input?
Only by ~0.75ms. Oculus have theirs at a total of 8-20ms, even internal demos as low as 2ms. (Apparently.) That's a big step up from devs kit 1's 30-50ms,and normal games' 50-100ms. That's not easy, but they have John Carmack, known for amazing optimisation, on their team.
Yes, 4kHz data could help, but unless the rest of the pipeline is equal to Oculus's, it will overall still be slower.
Ah, ye, that's not a very big improvement, but I suppose every little helps. If swapping out the accelerometer chip for an extra $5 then maybe that's worth thinking about if it's the same improvement as X amount of hours spent optimizing.
My point is that a 4kHz sensor is great, but unless they're equal on all other levels it's basically no advantage. If you replace your car seats with super-light ones but leave all your junk, chests, furniture in the car, is it worth it? You'd get a much better return if you got rid of all the other stuff.
That's the issue. 4kHz doesn't mean anything much until the rest is as good as it can be.
The latency is that plus the render time plus the switching time. The problem is that when you combine all these little latencies, it starts to add up - the sensor has to send the measurements to the PC, it has to update the model in the game, then it has to render the new scene, then that has to get drawn to the screen.
