No, not "reaction", "perception". (Reaction to unanticipated events
is much slower, 1 to 2 sec. Reaction to anticipated events can be
around 250ms. But we are not talking about reaction, because
perceiving a delay doesn't require any reaction.)
This:
https://www.britannica.com/science/time-perception/Perceived-duration
says 0.1 sec of visual experience is needed to perceive time duration.
And there are other similar sources. It is also consistent with my
own experience, from the time when I measure performance of
bidirectional display and compared it with my subjective notion of
"delay": anything below 100ms was barely tangible, anything below 50ms
was perceived as "instantaneous".
