I have the new Razer 8000 Hz prototype gaming mouse on my desk.

[Chief Blur Buster]

i put real time and high io priority on the thing and still notice 8k+

Try a slightly higher priority is best -- you don't want to starve the mouse driver.

There must be quite a lot of imprecisions in that software.

"Enhance pointer precision" is acceleration, but even disabled, seems Windows 10 still has a bit of residual acceleration.

Open registry and check these values, backup before change it. You can edit manualy, or download .reg file to easy fix with just double click.

All combined, it's normal to see poll counters vary by about 5-10% because of Windows non-RTOS weak links. Not the mouse' fault.

Yeah, not surprised at all. Just more factors people need to take into consideration when questioning metrics.

[howiec]

i put real time and high io priority on the thing and still notice 8k+, even a 10k read, but the adjacent number is a 6k, so I guess that evens out lol.

Realtime process priority is just a high priority. Standard Windows is still not a RTOS.

Keep in mind that process priorities are just relative attributes, so as Chief said, be careful when choosing realtime.
In some cases, you're better off lowering priorities of non-critical / non-resource/time-sensitive processes vs increasing, say a game, to realtime.

Could anyone provide data regarding the Viper 8k's click latency? Namely where does it fall on Overclock.net's list:

Table
Associated thread

If a mouse doesn't fall on the first page it's basically invisible to me.

I am also curious, given how cheap / early some of the mice near the top are, what is preventing companies from putting emphasis on achieving lowest possible click latency (and sensor motion latency)? You can find some big name companies with mice very down the list. I understand motion analysis is somewhat complex, but surely a button press is pretty simple matter, isn't it?

I wouldn't trust that list to be very accurate since it's just a compilation of other people's data which likely comprises of varying types and levels of test methodology and control.

If you're talking about purely the time it takes to electrically register the mechanical button actuation, then ideally you need to create a fixture that at least:

• automates the button press (with a consistent timestamp relative to motor actuation vs button depression)
• records time when click data is present on USB data line

If you trust Razer's marketing, they already state a 0.2ms click latency.

Well, they also state "<0.125ms click latency" here so maybe it's improved in gen2:

I would take the latter with a grain of salt without further clarification though the number itself seems quite reasonable.

Every company says it has low click latency. I mean no disrespect to Razer or TheFiend but I rather get it from a 3rd party.

yeah i only use it for smaller programs

my numbers are not like that. what do they mean? if i post a screenshot would you be able to translate how much accel I do have? I don't want to change if it alters my muscle memory even if i've only used win10 for half a year.
