I play a lot of video games. In Tekken e.g. Heihachi has a move called OTGF. The input sequence is listed as f,N,df+2. Each of those movements must be done in 16.6ms or it doesn't work. On an 8-way joystick, there are only 4 switches for the cardinal directions. That means the final movement of df+2 requires hitting the d switch, f switch, and 2 button within the same 16.6ms window to count as simultaneous.
There are players that can do OTGF move every time they try.
My audio interface for connecting my keyboard/guitar to my PC is USB-C. I tried USB2 devices and find they have too much latency. It's very noticeable. USB-C has 1ms latency or less.
It's a world of difference playing FPS shooters online between a 50ms ping and a 100ms ping. If you care about your aim, 100ms ping is barely playable.

Are you sure that's not just USB 2.0 interface being shit ? USB2.0 is certainly fast enough to have sub-ms latency.
I actually wondered about how to go with testing USB interface latency, maybe I should test mine when I have slow weekend...

That has nothing to do with latency. Human nerve conduction velocities just aren't quick enough for things like that to be done closed-loop under the control of the brain - it's just physically impossible.
Although the person doing the action may feel otherwise, that's just a well-trained sequence of actions performed open-loop.
I remember playing CS at the turn of the century on French or UK servers with 100ms or a bit more without problems, could it be that the problem is that now we are sending more stuff than before?
I have friends who still play (making it 20 years). They're at a level where playing on public servers gets them banned for cheating (some are/have been semi-professional).
Any latency, whether it's hardware, software or server, drops their performance significantly. It's at a point where they only play/practice under prime conditions, as their sensitivity is such that they will throw themselves off by practicing with more latency than they normally do.
In FPSes in particular, every millisecond of latency typically translates into peeker's advantage due to how lag prediction works. Or sometimes disadvantage, in the netcode that is poorly implemented or optimized for poor connections. It also depends on the movement velocity.
In games with really bad netcode it can get ridiculous, influencing the entire gameplay - for example in PUBG beta, which had about 200-300ms of actual client-to-client latency due to the very low server tickrate, you had to avoid running directly towards the corner to look around it, as enemies could see you running out in the open for a split second then rubberbanding back.
