I've actually been curious about getting a wireless keyboard recently, but wondered about how big of a latency impact there would be. Normally I use IDEs that definitely add a bit of sluggishness into the mix by themselves, but something compounded on top of that would probably make it way more annoying.
A quick search lead me to this site: https://www.rtings.com/keyboard https://www.rtings.com/keyboard
It does appear that they have a whole methodology for testing keyboards: https://www.rtings.com/keyboard/tests/latency https://www.rtings.com/keyboard/tests/latency
For what it's worth, it seems that well made keyboards don't have too much latency to them, even when wireless (though the ones that use Bluetooth are noticeably worse): https://www.rtings.com/keyboard/1-3-1/graph/23182/single-key-latency-graph/razer-pro-type-ultra/29787 https://www.rtings.com/keyboard/1-3-1/graph/23182/single-key...
Just found that interesting, felt like sharing. Might actually go for some wireless keyboard as my next one, if I find a good form factor. Unless that particular keyboard does something really well and most others just have way worse wireless hardware in them.
- Night_Thastus 3y agoIf you get a modern wireless keyboard with 2.4 GHz wireless and use that instead of blutooth, the latency can be great - like you saw. Blutooth is still crap though, avoid that if you care about latency. Or reliable connections. Also be aware that despite being able, not all keyboards poll at 1KHz. My old wired keyboard polled at 66 Hz. My current wireless keyboard has a single-key latency around the 1.7 ms range. Better than many wired ones!
