What could be causing this disparity in computer mouse behaviors on my laptop?

I've got two computer mice which, in various games, exhibit the following behavior:

The cursor begins moving at exactly the same time I begin moving the mouse, but the cursor ends its movement slightly after I finish moving the mouse.

Meanwhile, I have a third mouse which does not exhibit that behavior. Instead, cursor movement both begins and ends simultaneously with mouse movement.

(I'm simplifying a bit, because I'm not actually talking about cursor movement, I'm talking about rotation of characters in first-person-shooter games. I haven't been able to verify whether this occurs in other games with actual mouse cursors--the movements I have to make to detect the effect are too large for that.)



The terrible thing is, the one mouse that moves exactly simultaneously with me is a mouse I hate. It feels like it moves inconsistently--often the movement on screen is not nearly as much as I expect based on how much I've moved my arm, other times it seems far too much. In fact I've just tested it out and indeed, quick movements move the cursor proportionally further per inch-moved than slow movements do, for this mouse only. The others (the ones with the problem) move the cursor exactly the same distance no matter how quickly I move them. Mouse acceleration is turned off, btw.

When I've asked about this in other venues, typically people ask about dpi settings and whatnot. By whatever amazing coincidence, all three of the mice involved are ones that do not indicate a dpi setting in the control panel. But fwimbw, mouse sensitivity in windows is set in the very center--the sixth tick IIRC. And mouse acceleration is turned off no matter which of these mice I'm using.

Also: This effect occurs regardless of in-game graphics settings, including v-sync, and AFAICT, regardless of Nvidia Control Panel graphics settings, including v-sync and g-sync.

All three of these mice are optical, and all are clear of dust etc.

Yeah, it's switched off for each device (as mentioned in post :) )
