Yeah at 120hz each frame is 8ms. So you're only missing a single frame around 30% of the time.

I certainly want my latency as low as I can get it. But I'm pretty skeptical that anyone is truly feeling the difference of a couple ms.

This[1] study suggests image framerate does not significantly affect our ability to perform predicted moves accurately in time, above a certain minimum which is lower than 24 Hz.

Moving the mouse and then pressing a button, or pressing one key and then another, are both cases of predictive moves.

So it seems one shouldn't rely on framerate when talking about the limits of sensing input lag, at least in general.

Try musicians that are used to playing extremely high speed semihemidemisemiquavers.

We notice latency. Neil Peart could almost get sample-precise timing, he was so godlike.

Humans are good at predicting stuff, and they can notice when the expected doesn't happen.

But I wouldn't necessarily say that people can notice it everywhere in every state of mind. The medium, context etc all matter a lot.
