Hrmmm. I’m not sure this sentence even makes sense. I’m not sure what the definition of 0ms input lag even is. And I say this as someone who has deeply profiled true end-to-end input/output systems. 0ms relative to what exactly?
If you spend 20 minutes getting used to something you could maybe tell the difference if 3ms of input lag was artificially injected. Maybe. But that’s an exceedingly small value and if I had a toggle switch that turned it on/off I’d bet against you being able to tell when it’s on.
It does depend on the context. In a game like Guitar Hero 3ms is going to be exceedingly difficult to distinguish imho.
At the same time, sure, we easily compensate.
This is a deep and interesting enough topic that you could publish a pretty good and valuable paper on what the JND is for poor, average, elite, and “professional” players is.
If the line is 3ms for pro I will gladly bet the over!
". In general, human speech is jammed by giving back to the speakers their own utterances at a delay of a few hundred milliseconds. "
The total lag is almost certainly an order of magnitude above.
Edit: I can also tune a guitar by plucking two strings at once, but I can't by plucking them one at a time.
This really has nothing to do with noticing the absence or presence of a 3ms latency difference in a situation where your baseline is already dozens of ms of latency in the best case.
nothing is worse though than a rhythm game that can't keep proper rhythm itself.
3ms is how long it takes sound to travel a meter.
Do you notice the difference in audio/video sync between sitting in the front or the back of the cinema?
rhythm games are literally scoring your timings, a cinema offers no such equivalent of a scored feedback loop.
No, I wouldn't notice 3ms on the lips of an actor. Drummers are known to be able to perceive 1-3ms differences in timing; again, a tactile action.
If a human is involved in the action their sense of rhythm and prediction takes over to allow for manipulation within those timescales. It's not uncommon, either.
You are claiming that someone can tell the difference between playing the game oneeter or two metres from the speakers.
Put another way, on a large stage the sound from the bands monitors takes ~10ms to reach the drummer.
I don't have data, and neither does anyone else here apparently, but in the absence of evidence it seems exceedingly likely that any perceived differences due to 3ms latency (difference ?) are placebo. We know that placebo is real and large so unless someone has an experiment that tries to account for this (e.g. properly blinded) my prior is that you can't tell when playing a rythm game whether the speaker is 1m or 2m from you.
I don't think we could tell direction based on the distance and less than 1ms difference alone.
Like tuning strings by hearing when you can pluck both strings at the same time, vs doing it using absolute pitch.
