    Oh nice. Probably OpenCL is not far implemented in the free driver stack but anyway. I used darktable and quite liked it. So some accel won't hurt, even if you probably need the blob drivers for a real boost.
    Stop TCPA, stupid software patents and corrupt politicians!

      Benchmarks

      Are there any benchmarks about how much OpenCL improves speed?

        darktable and OpenCL (updated)

        Many readers will have already heard about GPU processing and the fact that darktable can make use of OpenCL to improve performance. As we still lack a detailed documentation of that topic, please find here a few explanations and howtos. The Background Processing high resolution images belongs to the more demanding tasks in modern computing. Both, in terms of memory requirements and in terms of CPU power, getting the best out of a typical 15, 20 or 25 Megapixel image can quickly bring your computer to its limits.

          In order to have OpenCL with the FOSS drivers work from T.Stellard on the LLVM has to be accepted upstream, right???

            I don't know if speed is all that important. I chose nx2 over lightroom because of control points and d-lighting. Speed is nice, but features are nicer.
