Typically the wireless mice connect over noon-bluetooth wireless protocols and offer bluetooth as fallback, if at all.

Click-to-screen latency is a combination of reporting rate, polling rate and latency within the software stack. Default USB HID polling rate is 125Hz so if you don't do anything extra on top this is what you get anyway. Even higher grade "office" mice offer higher reporting rates than that, "gaming" mice can easily be 1 kHz.

I always thought this is a rule of thumb, but then I learned that wireless gamepads for popular consoles (back then it was PS3/PS4 era) don't really follow that pattern. I came across multiple tests where older wireless PS controllers and xbox controllers were consistently more responsive in practice.

For modern ones there are some cool posts like this one [1], where most of the time there "were no statistically significant difference", or even wireless was more responsive.

Gamepads always impressed me - they can deliver insanely good response times while streaming high quality audio with no lag. I never found other BT accessories for phones/computers that were even close to that smooth experience.

For pro gaming perhaps the difference would make the slightest difference. For casuals, let alone office workers, the difference is 0 (writing this with a mx master 4 next to me).

Saying this as someone who has tried dozens of mice in my life. Last corded-one, bought for my son yesterday (razer cobra minecraft edition). I don't think I'd be able to tell the difference between wired and wireless in a blind test.

or you can just use wifi dongle one

there is no reason not to, even pro player in esports is using wireless mouse

the technology is there even for top 1%

Dongles are indeed not perceivably different than wired in principle. However, you may have more latency variability, or even unstable connectivity, depending on what adjacent usb ports are doing, due to interference [0].

I have had cases where dongles were practically unusable in my setup, up to completely losing connectivity when transferring data through an adjacent port.

never happen to me in this year

maybe in 2012 as paper suggest, also millions of gamer also use these today

there is exist mouse gaming that have 4k,8k polling rate right now

You also want to have Nordic MCU specifically

I have had issues with an otherwise decent 2022 computer, had to arrange usb connections in specific ways to avoid brief connectivity drops. It did not happen all the time, but it did happen. But the worst problems were older ones.

USB ports have probably better shielding nowadays. But even so, the protocols and radio frequency ranges are still the same, so if I do not see a specific test on that (measuring latency distribution while adjacent port busy) I would not trust it if latency was important, even if it "feels" the same. And not all of us have professional gaming equipment or otherwise of much better quality.

If adjacent ports are not busy there should not be an issue nowadays, probably.
