I have used Rhino 5 64 bit for six months with no issues.
Suddenly my nvidia 310M is no more recognized by 64bit version, while no problems occur with 32 bit and rhino 4.
The integrated Intel HD processor is the only that appears in opengl panel.
Nvidia control panel settings are set to high performance graphics, and I’ve also tried the solution shown in “graphics-problem-64bit-only/1477” topic 1
All thi happened using a laptop Asus k52JC, geforce 310M with nvidi optimus, windows 7 64bit
Thanks in advance
