Blender 2.75 Released With AMD OpenCL Support, Multi-View/Stereo 3D Pipeline

[xeekei]

Try this:
CYCLES_OPENCL_SPLIT_KERNEL_TEST=1 blender

It might work... but then again opencl is done for gcn arch so you might better of with cuda.

There is updated opencl page for blender cycles:

I know CUDA is better for Nvidia. I just wanted to test the new feature.
