I suspect is not Rhino problem, ignore my first post and solutions from my first post, that’s another problem !!!
Problem is, you run Rhino hooked in to Intel GPU and not permanently with Nvidia GPU, or Nvidia Optimus changes the Nvidia-GPU to Intel-GPU at run-time. (see picture two under Ombreggiata, here Nvidia should be listed)
Search on web for “Intel Nvidia Optimus” for CAD
or see here -> (very good) result:

That is or not ??
