As someone who once plays games very regularly, I get laughed at when I say that I can feel the different keyboard input latency between wired and the bluetooth stack in windows / Mac OSX.

Other people -swear- that its impossible to feel the difference, however I can't provide evidence other than 'blind testing' which I have passed. How do you know if you're feeling input latency or response latency with your devices ?

It’s funny but I think am unusually sensitive to latency in games.

I had a “gaming” laptop which had about 30 ms of latency on the screen which I measured by hooking up multiple monitors, running a clock, and photographing the screens. (I got photos where there were different numbers on different screens!)

I was playing League of Legends at the time and it always seemed like I’d get hit and there was nothing I could do about it. Once I started playing on the external monitor I started playing a lot better.

Earlier I was playing Titanfall on a Samsung TV and just getting killed despite Titanfall being forgiving to players who suck. Sure enough I put the TV in “game mode” and all of a sudden I’m “in the game”.

I’m a weeaboo so I play a lot of turn-based games, Musou games and others that are not twitchy but I find there are occasional of single-player games such as Sword Art Online: Fatal Bullet that I just can’t progress on without the TV being in game mode.

This is despite the general advice that you shouldn’t use game mode for single-player games. Now I don’t know if other people can anticipate the future better than I can and tolerate latency better (I am a schizotype) or if a lot of people play multiplayer games with high latency and suck at it and don’t know why or if a lot of people try multiplayer games and quit because of their monitor or TV.

I 100% believe you, I understand exactly what you mean.

Its not just you. Someone gave me a keychron keyboard to test out because they thought my using 'mainstream' brands that weren't lubricated or whatever was bad, and even wired the input latency on the keychron was worse than relatively cheap logitech (G613) and razer (blackwidow mini v3) keyboards on 2.4ghz. I don't know if its their USB polling or what but these well reviewed keychron keyboards were basically completely unusable to me.

RTings.com usually includes tests of latency in their keyboard reviews under 'typing experience' which is helpful if shopping.

Maybe one day if keychron cares enough to fix it I'll give them another try.

If you're playing 128th notes at 178bpm each note is 11 ms. If your BT headphones have a 30 ms latency everything you play will be off. The only BT headphones that work for music are AIAIAI headphones which require their own transmitter and receiver. They still have a 16ms latency and barely work.

General BT is useless for music.
