Question

I’m wondering how to get true mouse displacement with windows.

For example, I could save the position of a previous mouse position, and request the new position, and subtract the latter from the previous. But this would not give me true mouse displacement.

Imagine the previous cursor position would be the maximum x coordinate of your screen resolution, and the user is moving his mouse to the right. Is there still a way to capture the true mouse displacement then?

Thanks

It is not possible to track physical mouse displacement with the Windows API. However, DirectInput provides features to keep track of it. You can also ‘fake’ it using only the Windows API, using the neat little trick in the answer of SO user DXM
