At the moment, it is only possible to set the mouse cursor speed for both 3D mouse and system mouse together in Settings - Mouse pointer speed:

The stereo interpreters at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) in Switzerland have the following problem:
- When the speed for the system mouse is good for them to work productively, this speed is too fast for the 3D mouse
- When the speed for the 3D mouse is good for them to work accurately, this speed is too slow for the system mouse
The stereo interpreters mostly work with the 3D mouse. However, from time to time, they need the system mouse to select a combo box item or click on a button in a form, or to click on a button in the ribbon.
--> It would be good if the mouse pointer speed could be set separately for 3D mouse and system mouse
