    Maybe because OpenCL is always second class citizen on nVidia hardware? Example: http://www.luxrender.net/forum/viewt...hp?f=17&t=9646

      Not really, results are just as unspectacular on AMD cards in handbrake.

        I suspect this is really meant for AMD's upcoming HSA architecture that integrates the GPU more closely in the CPU.

        I think they're supposed to come out later this year, and this will give AMD a benchmark to point to which shows them beating out Intel.

          If i remember correctly the OpenCL Part is only for the lookahead and that is not really important, but the DXVA decoder brings a benefit.

            The most optimal way would be to load the video into the graphics card memory and decode, composite and post-process on the graphics card. The graphics card is much better suited for graphics calculations and it frees the CPU for other tasks.
            AppGeeker handle this job well, tool.
