This isn't a game, but I'd like to convert my Windows Desktop Sensitivity to MacOS. Currently, I use 400 DPI with the mouse slider set to 8/11 (multiplier of 2).
This is the only way I have achieved same DPI between Warframe and Desktop.
The next step is to link Windows Desktop and MacOS Desktop.
On MacOS I use a utility called LinearMouse (https://linearmouse.app/)
It has the ability to completely disable MacOS mouse acceleration:
However, even with my mouse DPI set to 400 DPI (Razer Mouse, using Razer MacOS open source software), the sensitivity is still decided upon by the "Speed" parameter here, from 0 to 1.
As far as I can tell it is linear. Would you be able to make a calculator to convert between Windows Desktop (Pointer Speed + DPI) to MacOS (Speed + DPI) to be equivalent? The only method I have for now is trial and error, measuring the left to right movement of my mouse on my 2560x1080 29.5" display, which is about 3.2 inches. Then, I dial in a Speed setting that roughly equates to left to right movement on MacOS on the same monitor, to move the mouse across the screen by moving 3.2"
Thanks in advance @DPI Wizard
