That's not quite true: 100ms might be the limit of human reaction to unanticipated events, but if you're doing something repeatedly, the delays become easier to notice. I don't know about 10ms exactly, but 20-30ms - definitely. It will annoy some people more than others, but it creates subconscious impression either way. We have just recently fixes a related bug in Company (regarding increased visual latencies), with multiple reporters and benchmarks.
