Mouse wheel delta values

[aleksazr]

Hello everyone,

 

When we rotate the mouse wheel, most mice send a ±120 delta value (as those who use WM_MOUSEWHEEL know, for example).

 

However, there are much more precise mice that send only ±1, meaning their wheel has no detents.
But that information (the delta value) is hard to find—even on the manufacturer’s website.

 

I want to buy such a mouse, but I don’t want to buy blindly, so I’m opening this topic. It might help me and others too.

 

Logitech 3/4 and Keychron M6 have MagSpeed—the wheel spins freely without detents—but that doesn’t guarantee they send ±1 (they might just accumulate the values and send ±120).

 

So, before I waste 135/60 EUR, if anyone has these mice (or other models) and wants to test them with Mousinfo.exe (by Microsoft):

 

Mousinfo.exe is part of the IntelliPoint software package and can be found here: http://www.oldversion.com/windows/intellipoint/
Download, for example, the latest version, then open (don’t run) the EXE (e.g. with Total Commander, Ctrl + PgDn), subfolders: ipoint → setup → files.
You’ll find mousinfo.exe there—just extract it; it’s not an installer.

 

If someone wants a direct link, send me a message—I’ll share my Google Drive link for Mousinfo.exe, version 8.2.

 

IntelliPoint, by the way, is outdated; it’s now called “Mouse and Keyboard Center 3.0” –
https://www.microsoft.com/en-us/download/details.aspx?id=55977
There you’ll find mousinfo.exe under mousekeyboardcenter → setup64 → files.

 

So if anyone doesn’t mind, please post here which mouse model you have and what wheel delta it reports—if it’s below 120.

 

Thanks!

 

P.S. There’s no online test for wheel delta, I couldn’t find one.
There are for polling rate: https://cpstest.org/polling-rate-test/

I think MX Master 4 has free-rotation wheel, but how it reports the delta might be just an implementation thing.

It doesn't have to translate to different motion on screen

What are you using the mouse wheel for that needs uber precision on it? I have use a variety of mice and have never found the wheel to impact what I am doing.
