I recently got a new 2016 tMBP and started learning to use Blender. What I noticed is that using GPU to Cycle Render is really slow, much worse than CPU Render. The BMW benchmark takes about 12 minutes in CPU, but with GPU, it takes over an hour. Is there a way to make rendering with GPU faster? i.e. install drivers, etc. Also tried to use Blender in bootcamp, but for some reason, Blender cannot detect the Radeon Pro 460, so I'd be stuck with CPU rendering in Bootcamp.
