Orbit zoom and rotate tools working very slowly

i have windows 10 running i7 6th gen system with 4gb 950m gtx graphic card.
since a week my system is experiencing serious problems with zoom, orbit and rotate tools… they work annoyingly slow. its happening with very simple models too! like a single rectangle.

version - sketchup pro 2016

The consensus here is that a recently released Nvidia driver is causing this issue, and that rolling back the driver might help.

I don’t use Windows 10 yet and I only update my drivers if I experience problems. Trying to follow the “fix only what is broken” principle.
