Brains work with latency all the time, and are very good at latency hiding - as long as the latency is predictable. Jerkiness is bad, keeping things smooth even at the cost of higher average latency is usually worthwhile. Indeed, brains are so used to latency that you can trick them to think reaction happened before the action that caused it (e.g. button press -> light up).
