How to enable OpenCL? Only CUDA is visible.
Windows 7 64-bit
Core i7 3960X
On another computer with AMD graphic cards (AMD/ATI 5450, AMD/ATI 6570) I can't even set GPU rendering.
GPU Caps Viewer shows on every platform that OpenCL is available.
Not sure what your end goal is here, but CUDA is the better supported solution, both on nVidia cards and in Blender in general.
My end goal is to use OpenCL:) CUDA is not available on AMD. I noticed that OpenCL is available on older releases including 2.63, 2.63a, 2.64, 2.64a, but it's not supported on 2.65 and 2.65a.
OpenCL On hold
by the way suggesting Cuda over OpenCL it's just a downgrading, OpenCL is far more powerful than Cuda that is simply a framework for Nvidia GPUs; the real difference is that OpenCL requires more dedication and resources than Cuda to give/code an equivalent program, but in practice and in production OpenCL is always better.
The recommendation of CUDA over OpenCL is based on which was currently better -supported- by Blender not which was more powerful in its potential capabilities.
