Hi
I found someone in another thread:
It seems he had the same issues with Technical View.
One of the comments on this thread from @jeff sent me in the OpenCl direction of research.
I tried downloading the Intel OpenCL Runtime and installed that with no difference.
I downloaded a very useful program which has built in tests for OpenGL and OpenCl(Gpu and CPU) here:

Only the particle and Hair tests don’t seem to work on OpenCL-CPU on my system.
GPU Caps also shows that I am using OpenCL 1.1 for CPU and OpenCL 1.2 for GPU?
From comments on the above linked forum it seems asif @Przemas only managed to remove the slowness on a fresh install of Windows7.
This makes me think it must be a driver issues?
Note: I have also been unable to ever use the Vray RT OpenCL option. Only RT Cuda works.
Is there perhaps another OpenCL driver that Rhino requires for Technical Viewmode?
Anyone with any ideas would be welcome. Michael VS
