heh not really sure they care about opencl, but do as said:
https://devtalk.nvidia.com/default/topic/522835/linux/if-you-have-a-problem-please-read-this-first/

OBSOLETE COMMENT, PLEASE SEE COMMENT #5

With 340 drivers, I made a benchmark in Darktable comparing OpenCL on
and off 46,688 seconds vs 4,174 seconds.
The operating system is Fedora 20 and the CPU is an AMD Phenom II X4 965 BE.
Here the results

I am waiting for a your response.
