I haverun your request with a Microsoft cable mouse, a Microsoft wireless mouse and a3D Connexion Cad mouse, as far as I can tell all perform Rhino’s rotate viewwith the same amount of jerkiness.
At fullextents the Space Pilot appears not to rotate at all.
Zoomingin very close all using Rhino’s rotate view rotate much better but still with adegree of jerkiness. The Space Pilot at the same zoom level as previous rotatesnearly as the mice, but at least it rotates. Likewise all other space pilotfunctions.
Openinga model of 841 KB, and carry out the same tests. The Space Pilot works fine,and so do all 3 mice. So could it be that 16GB of ram in the Dell 6800 is not sufficient?
Anyother requests – questions, please do not hesitate
