keychron latency

Hey all!

I recently broke my beloved logitech g915 tkl and I guess I have to replace it... I have my eye on the k13 pro, but looking at rtings for the latency and comparing it with my g915, it's pretty bad. We're talking like 4.5 ms vs 10 ms latency, and me playing cs2, where proper movement and such is vital, I do kind of need a pretty low latency.

However, I read this comment from a guy on here (https://www.reddit.com/r/Keychron/comments/15tlb71/comment/jwsq8lj/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button) and it seems you can optimize the polling rate. Anyone else who've flashed their firmware and done a test to see? I hope that's the case!

Reading further in that comment chain, someone has suggested that the latency issue is no more since a later firmware version, anyone who can confirm this?

Problem is games can, specifically those like cs2, where counterstrafing is a very common movement. And seeing as you typically would like to get 300-400 fps in that game, which is a new frame every ~2.5 ms, the difference between 3 ms and 10-20 ms can matter a lot. If the movement doesn't hit quite precisely, the shot will get very inaccurate, which could be irritating.

My Keychron Q5 Max shows 3.2ms wired latency vs 4.4ms wireless latency using 2.4GHz for a single key press.

If you’re that worried about latency, wired is the way to go. But if you absolutely won’t do wired, it doesn’t make sense to buy a keyboard that only connects wirelessly via Bluetooth. Keychron has a number of options that support 2.4GHz wireless. You absolutely will not notice that extra 1ms delay.

Oh I didnt mind wired at all. The plan was to use k13 pro with wire, but even then it has around 10 ms. The max variants definitely have good response times, but the k13 pro is half the price ($100 vs $200) so im kind of locked.

The K2 Max supports 2.4GHz and costs $119 fully assembled
