GPU Rendering with Mac Book Pro with AMD Radeon R9 M370X 2048 MB? I just bought the mac book pro with the AMD Radeon R9 M370X. Unfortunately rendering is quite slow. I've read in different forums that i need to switch to GPU in user preferences -> system and change to GPU computing on the right hand side of the screen. I did it but the rendering process is still slower than rendering with just cpu. Can sb tell me what i am doing wrong?
Thanks a lot!!

With GPU rendering it's usually best to increase the tile size to about 256x256.
That way you're not going to-and-from CPU and GPU memory so much.
