How to change mouse resoluion? It should be simple

Hello,
I bought a new a4tech j95s mouse and sensitivity is too high. I set it to lowest resolution on a Windows machine, saved settings to the mouse's firmware, but it's still too sensitive. Linux only offers some acceleration, but that doesn't affect the sensitivity at all... I set accel ratio to 1/10 and various thresholds, but it doesn't change at all... I only want a simple resolution scaling. Like, tell X to map my mouse cursor on a screen of double the resolution and then scale it to my true resolution. That is a really simple method to solve this pain. It must be doable. Is anything like that actually doable?

https://wiki.archlinux.org/title/Mouse_ … h_libinput

tell X to map my mouse cursor on a screen of double the resolution and then scale it to my true resolution. That is

input mapping and not possible on X11 (but the approach wayland takes)
See the above link on how to manipulate the libinput pointer speed, basically choose "flat" and a small enough "Accel Speed".

Edit: the xset factor has a threshold (iirc 6 by default) so for the first 6 (?) pixels there's no impact at all.
