[EXPERIMENT]Keyboard latency at different debounce settings
Posted: 09 Feb 2020, 18:38
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

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
EDIT:
Decided to test some of my other boards and got a few surprising results 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
UPDATE:
finally got my hands on g pro romer-G
here are the results
