I think your system isn’t using the nVidia card. It’s probably a dual card setup which has a low end intel graphicchip too, and Rhino has never truly mastered the art of using the right one. So go into the advanced settings of the nVidia driver and add Rhino (or adjust Rhino settings if present) and then scroll to the bottom and set the “Primary OpenGL Graphicprocessor” to the nVidia card.
(I don’t have a profile for Rhino on this system (My workstation) since I only have one GPU, so excuse me using “Adobe Acrobat” as an example 
)
