Keyboard latency testing results

testing methodology

Game: Fortnite 240fps locked in-game exclusive fullscreen
Keyboard: Ducky One 2 Mini (adjustable debounce) 1000ms polling rate
Camera: Note 9 960fps
Monitor: Dell s2716dg

I am hitting the key by flicking my finger. Easy method to get the point of actuation with id say 4-5ms accuracy
I stop counting frames at first on screen reaction so the 144hz refresh rate should not cause any unwanted variations

sample video:
Results:


These values do not represent the actual latency of the keyboard but the whole chain from keypress to display on my particular setup
However, the results still show that the debounce settings does in fact have an effect on keypress to usb latency
Surprised to see that the Corsair is faster than all of the ones i've tested so far because you'd think theyd use oem pcb's like any other just like they do with their power supplies

I will test the Logitech G-pro wired keyboard when i get my hands on it
Should get some interesting results because this board was shown to have 9 ms on a Razer keyboard in that GamersNexus video

Would be cool to see how this looks in practise..if you can see it at normal fps. Different keyboards start at the same time and you lay the recordings on top each other..playback at normal speed and 50% or something.

Do you have a PS/2 keyboard? I would like to see how quick interrupt based polling is

the feel when you're stuck using a 10 year old office mouse because you can't aim with anything else... FeelsBadMan

Just tested the iGK61p
~21ms despite having optical switches. The electronics and controller are probably low quality.
