I am using a SpaceMouse wireless and got (very) used to it so I am pretty much useless if I do not have it... But I digress. I recently tried to pan / rotate my 3D View using only the mouse but I am not getting a real time animation like when I am using the SpaceMouse.
I am using Middle Mouse Button to get the rotation. The part only change position at the end, not in-between. Just to be clear, I am only changing the viewpoint and I am not trying to rotate the part (Solidworks works fine for modelling).
I am pretty sure that this is something super simple. I am seen that in 2020 and 2018. Disabling the SpaceMouse plug-in does not help.
