Logitech touchpad T650 acceleration

There are separate pointer speed and acceleration settings, just no UI for all of them (I hope yet).

You can try to edit settings file directly (don't forget to backup it before breaking anything).

It's located in C:\Users\<user name>\AppData\Roaming\Logitech\SetPoint\user.xml and contains settings for all of your Logitech devices.

The T650 section obviously starts with "<Device DisplayName="Rechargeable Touchpad T650"..." line folowed by <params. That's where you can find the "ACCELERATION" parameter. It has a reverse effect, so "0" is the highest one.

The params responsible for Pointer Speed setings called "SpeedX" and "SpeedY" here.

 

I hope that was helpful for you,

Cheers.
