Subject: Re: Fwd: 'close' to getting opencl working
I am doing CPU opencl. I do not have a GPU. I am not worried about performance. I just want to be able to compile, to do testing on/off.
It may well be that VB does not support this. There are a few settings on the outside of VB, on how the VM is setup, PAE/NX etc. I do have that selected. I will look for other settings, and see if I can find current posts listing VB can not do OpenCL at all (hope not).
Jim.
