Lowest latency wired mouse?

Hard to find accurate benchmarks on this, but I don't see why it couldn't get down to 1ms at 1000hz via USB. Not 1ms to change on screen, but 1ms to change in pointer as measured by OS.
Thoughts?
 
Linus just dropped a video on this today. They used a Phantom high speed camera, 240hz monitor, and a homebrew timing rig. Shocking result of the day? Logitech wireless beats out the latest Logitech hero sensor.

 
That's what made the question... Hard to believe 15ms is as low as it gets - probably because it isn't. They should measure from mouse -> OS, excluding display.
 
Ps2 mice at high rate will be fastest. There was a ton of talk on this at overclock.net several years ago but I'll be damned if I can find it by now :(.

Oh, this was very eye-opening. The drop in performance on a regular wireless mouse like the Logitech MX Anywhere is crazy. I don't mind considering wireless gaming mice now.

PS2 has higher polling rates than 1000hz USB? How's that?

PS/2 doesn't do polling, it "interrupts" and immediately sends the signal instead of checking every X ms.

But polling at 1000hz should only add a maximum of 1 ms more lag compared to PS/2 polling. It has much more to do with the electronics inside the mouse. Also I doubt any new mice would even support PS/2.

Battle(non)sense did a video on this for keyboards comparing USB polling rate and PS/2.



He tested a Cherry keyboard that supported PS/2 and it had slightly less lag than while it used 125hz polling. But he tested a Corsair K70 @125hz and it had way less input lag than the Cherry keyboard and way, way less when it was set to 1000hz polling.


I doubt you'll find any mice with less input lag than Logitech's highest end gaming mice. I've never seen any tests showing other mice with lower input lag.

Maybe if you overclock your USB polling rate and use a wired mouse that sends accurate data while overclocked at a higher rate,
 
sharknice Yes, makes sense... So how can't Linus get under 15ms from lowest latency mouse -> screen? Is that all screen latency? At 1000hz the best mice should be under 5ms, the computer shouldn't add more than 2ms, the lowest latency displays another 5ms... So that's 12ms - and I think that's a liberal estimate. I'd like a clearer breakdown per component because hand->display latency is what matters (in this thread) be it click, mouse movement, or keyboard.

240hz is still 4.17 ms time resolutions. any different within 4.17 ms should be considered the same.

The game takes time to render everything which takes a lot of time, then the monitor adds some, sending the signal from your PC to the monitor, then the monitor processing the signal, then the pixels transitioning. https://www.blurbusters.com/faq/mouse-guide/
 
I figured I should post here instead of starting a new thread:

What is the lowest latency trackpad / touchpad? I'm guessing the Apple external trackpads are the best one can buy? I'm also curious about increased polling & latency in trackpads.

5ms between sending data is not the same ad data is at its goal after 5 ms

if i send a across the globe every 1 hour it does not mean the recipient got it after an hour
if i do the same to a guy standing right next to me it does not take 1 hour for him to get it either


I keep seeing these "math" arguments that because the math fits it must be right. But you need to understand what the numbers really mean in he physical world before you can make claims
otherwise you make stupid claims that if a pixel can change color in 8ms give no blurr on a 120 screen.
