I wonder if it is possible to match the sensitivity between Windows with 6/11 and 1600dpi on 1920*1080 and MacOS 14 with mouse acceleration off?

Since now MacOS 14 Sonoma has offered option to turn off the mouse acceleration. Actually there is also an app named Linearmouse can do that. But I'm not sure it's now possible to match the sensitivity on windows and mac now?

I don't have a Mac, but isn't the default setting 1:1, 1 count = 1 pixel like in Windows?

Unless display scaling is on, then it's 1:1 to the virtual resolution.
