I have been not that active with Blender lately, but I am trying to catch up with current development by installing Blender 2.79. Reading about all the improvements related to OpenCL I wonder what is the status quo for AMD GPU's on Mac Pro (AMD FirePro D300, D500, D700).
I have difficulty to understand wether all these OpenCL improvement are also noticeable when working with these GPU's and if you have to do something special for having these benefits ?
When reading this ... I am not sure what to expect on AMD Firepro?
Testing Activate OpenCL rendering For AMD cards on Windows and Linux you just need to select your GPU under file -> user preferences -> system. The split kernel will be used by default to give the best performance. To use OpenCL on other platforms, launch Blender with --debug-value 256 (either on the command line or by adding it to your shortcut). It will add a section "debug" in the render options panel. There you can choose the kernel (split or mega) and the platform (set to "all" to enable OpenCL for Intel and NVidia). Then choose GPU as the device to render in the render option panel.
