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!
The total lag is almost certainly an order of magnitude above.
". In general, human speech is jammed by giving back to the speakers their own utterances at a delay of a few hundred milliseconds. "
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.
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.
