Movement smoothness in pursa slicer

[ivan_ef]

I found significant difference in model movement smoothness when using space pilot pro and spacenavigator in prusa slicer.
Look at diagonal lines. first run is a spacenavigator and second is space pilot pro. First one looks more smooth like 60 fps, with unfrequent jumps. Second is more jittery like 30fps with more consistent moving.
Also tried both in Autodesk fusion and there is no difference between two devices (movement is not very smooth anyway )
What may cause such a difference?

And my eyes doesn’t fool me. I make a slow motion video comparison of model movement controlled by space pilot pro and then by Logitech mouse.
