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
I’m not sure what may have changed on your computer but it sounds like an update to Windows or the Nvidia driver may have been involved if it was working prior to this. Or was it an update to Rhino 5 x64 when you noticed this? I’m also curious if the GPU is seen in the 32 bit version of Rhino 5 which ought to be in the Rhinoceros program folder as well.
thanks so much for your reply.
I’ve just upgraded to sr6 with no positive changes, while with Rhino 5 32 bit (C:\Program Files (x86)\Rhinoceros 5.0\System\Rhino4.exe) all is fine.
I’ve recently updated nvidia drivers, but I don’t remember if the issue raised then.
