Scroll Modifer: How to deactivate Acceleration completly?

Hi Andreas,
currently I want to tweak the settings of my Logitech MX Master 4 - especially the wheel.

What I see in using my mouse wheel is, that it's pretty difficult to navigate a page (veritcally) to a exact position. It feels somehow random how the wheel responds.

When I turn the wheel pretty slowly it nearly makes not movement on the page (vertical). When I move it fast - but the same distance - it makes a lot of movement.

  • Is this intended?
  • Which setting would change this behavior?
  • Would it even make sense to deactivate that behavior?

In the Scroll Modifer: Smooth Scrolling (like Trackpack) I set the Acceleration Strength to 0 (see screenshot below).

Unfortunately the documentation hasn't helped me a lot, since it refers to old settings: Scroll Modifiers | BetterTouchTool Documentation

Have a great start in to the week.

Best regards,
Volker

edit: Just found a discussion about the same topic How can I completely disable the mouse scroll acceleration?

Okay, the "Scroll Modifier: Distance per Tick" does what I wanted. But it does not feel as good as intended originally :smiley:

Still wondering what Acceleration Strenght in the "Scroll Modifier: Smooth Scrolling (like Touchpad)" actually is doing? It seems that 0 does not deactivate it.

if you add the "Scroll Modifier: Disable / Reduce Scroll Acceleration" in addition to smooth scroll, the system acceleration should be gone.

Acceleration strength is basically additional acceleration BTT can add on top of the system acceleration. I'll change the description to make this more clear.

Thank you for the clarification Andreas.

Can you say a few words about the different parameters in the "Scroll Modifier: Disable / Reduce Scroll Acceleration" and what they do?

I cannot manage to get rid of the system acceleration.

Do your logitech mouse configuration possibly have high resolution scrolling active? (that changes the behavior of the scroll and might cause the default parameters to fail for the acceleration disable modifiers)

I would try setting Continuous Deacceleration Strength to 0.1-0.2 and the Reference Speed around a comfortable normal delta, then restore speed with Output Speed Scale.
