I posted about the random jumps here, but now I found this thread.
Also just noticed a micro “stutter” like twice per second… framerate is very high (just got a new computer) but zooming through the model isn’t smooth (Testmaxspeed shows 60 FPS). EDIT: V7 exhibits that same stutter, while for example Blender using a SpaceMouse does not, so I guess not a beta issue but still perhaps a Rhino issue.
