8000 Hz mouse, is it worth it?

[Vegasskill]

I think about Razer deathadder v3. This model has polling rate up to 8 khz.
Any thoughts guys about this model or 8khz models in general? Some say it's ok, some say it hurts performance.

Thanks.

I have the mouse and really like it. Some games, Unreal Engine in particular, can have issues with high polling rates and can affect performance. I've read that the higher the polling rate you want to match it with a high fps and refresh monitor. My monitor is 144hz so I run the mouse at 4khz but have to drop it down to 1khz for certain games like Fortnite and Rivals (both UE) ((Rivals season 0 was fine but having issues in season 1)). DeathAdder mice last me 5-6 years on average.

I dislike the DPI switch being on the bottom of the mouse compared to DeathAdder v2 which was on the top by the scroll-wheel.

over 1000 i pointless
same with 40000dpi
if your movements are that fast and need to be that accurate

getting movements updates higher than fps is needed, but at over 500 isnt going to get any later input for creating the next frame

1000hz is the max for usb 2.0
which is more than fine for k/m and controllers

Performance hog, not worth it at all. Stick to 1000hz or 2000hz at most

Considering every time a poll results in a move or click it fires off an interrupt?

Any performance hit incurred is going to be due to the higher CPU overhead, which is probably going to be more noticeable on slower CPUs.

But the mouse I usually use is a Razer Basilisk V3 Pro, running at 8000 Hz through hyperpolling wireless, and there hasn't been any performance hit that I've been able to notice on Linux with a 10th gen i9, which could speak volumes about slow CPUs being unable to keep up with the faster inputs, or could be an issue related to Windows.

It's noticeably smoother mouse movement.

A 1,000 megahertz polling rate has a response time of 1 millisecond. The game state should only update every frame, so we're probably saying that if you complete your input before the frame is done that it is fast enough.

Assuming a framerate of 144 F.P.S., a single frame lasts 6.9 miliseconds. 1 millisecond is well under half the duration of the frame. It's almost a seventh of a frame in fact. Granted, time is analogue and so are you, so there is some infinitesimal chance that a higher polling rate would allow you to catch an input in time that you otherwise wouldn't make, but we're probably saying it's so small as to be negligible.

II wouldn't worry about a peripheral having more than 1,000mhz polling rate.

If you really want the mouse for other reasons, you should be able to change the polling rate of your U.S.B. ports in the B.I.O.S., and if I recall correctly you may have to enable high polling rates in the B.I.O.S. anyway (so if you can't it doesn't matter).

hz is snake oil in terms of mouse specs, same with high dpi sensors. Build quality, sensor quality, response times, shape of the mouse, which switches the buttons use. These are things that actually matter.

your target hz for inputs as a rule of thumb should be double your monitor hz

thats partly why as standard a monitor would be 60hz and inputs are 125hz

if you have a monitor refreshrate below 250hz then run your mouse and keyboard polling rates at 500hz

this gives you at least two inputs per frame and keeps perf overhead and latency low

anything extra is going to eat up resources and even increase input lag, defeating the entire point

That's completely wrong, the higher you go in refresh rate, the more of an impact that sub-1000 Hz mice is going to have on latency, even on 120-144Hz there's a huge difference between the bare minimum and 1000 Hz.

When you cross into the territory of 360Hz, 420Hz, etc. then you run into situations where even 1000Hz isn't enough, it's exactly the reason why 2000+ Hz mice exist, it's not just a gimmick, it's actually beneficial for extremely high refresh rate displays used in competitive gaming. It's what it's made for.

Most gamers are fine with 1000 Hz and there is zero reason to go any lower than that either.

Isn't there overhead beyond CPU speed due to hardware interrupts halting program execution so the operating system can back up the CPU state, service the interrupt, and then resume application execution?

Thanks for all the comments guys. So I bought it. So far so good.

I like that the mouse is fully plastic in comparison to DA v2 where the rubber really degenerated after less than 2 years and was simply falling off, and the plastic texture seems ok and doesn't feel slippery.
Plus the mouse shell feels more solid(despite the smaller mass) than in DA v2, nothing creaks.

I am using it at 4000 hz polling rate on i5-10600 (6c/12t) with RTX 4080 and Windows 10 version 22H2.

So far, I have tested these: Quake 3 Arena, SOMA, Shadow of the Tomb Raider, and Call of Duty MW 2019.
At a 4 kHz polling rate, everything seems fine for now.

I did not test the 8 kHz option yet.

[skOsH♥]

I just use 1kHz and it's fine for me

Higher polling rate will use more cpu and could cause issues

[Bing Chilling]

i use a g305 and its a 1khz mouse. its great, i have tried higher polling rate mice but they are mostly marketing after 1khz, if you were a pro maybe you could tell the difference but i highly doubt a normal person is going to be able to tell any difference.

even 500-750hz is basically unnoticeable to me at 144fps/HZ
and i use 750hz to save battery life of the G305 most of the time.

also one thing to mention is the higher polling rate will increase CPU usage, not by alot but it does use more cpu as it needs to communicate with the mouse more often then lower
8000 polling rate means it communicates with the mouse 8000 times a second.
