The Lowest Latency $600 keyboard?

Crossposting from some other forums. https://linustechtips.com/main/topic...ncy-keyboards/

"A friend of mine, doing perception research in neuroscience, pointed out a keyboard they use in experiments with below 1 ms of latency: http://www.empirisoft.com/directinkb.aspx. It's not only claimed by the producer - they validated it, and the same tests showed around 8-16 ms latency for almost any other keyboard due to USB polling rate.

I was wondering if anyone had experience with gaming with ultrafast keyboards in games along the lines of CS?

Conventional wisdom says that it should make no difference, the same used to be said about monitors going above 60 Hz and then above 120 Hz and I am curious of hearing about the experience of people who actually tested them, preferably paired with high refresh rate monitors."

Is this snake oil? All keyboards have contributing factors such as Keyboard Scan, Contact Bounce, Debouncing, ect that all increase input lag.

I dare you to find any real-life reaction differences between a cheapest membrane keyboard you can find on lowest possible refresh rate and ultra-high mechanical keyboard with 1000+Hz refresh rate on Red switches.

I double dare you. Stop believing in marketing gimmicks.

Calm down sir this is a Wendy's. There actually have been two different types of Keyboard Latency testing that I know of.

First is the famous FSB test. https://danluu.com/keyboard-latency/

And the second common method of testing keyboard latency with 240hz camera.

Both achieved different results with the former saying apple magic usb kb has the lowest latency while the latter saying gaming keyboards are faster.

At that point PS2 and work on your own bodies personal latency, you can measure the differences but the difference is mostly going to come down to PEBCAK, lol

From my experience, the KB latency doesn't matter that much, unless it's really bad. Got my hands onto a cheap keyboard once (iirc it was Drevo-something). The delay is 30ms+ due to debouncing (or so they say in an official statement). It was quite perceivable in Quake. The QFR feels lightning quick in comparison (hence it's name, i guess?).
