I am rendering using OpenCL Cycles Blender 2.77.
Graphic card http://videocardz.com/40226/sapphire-announces-radeon-hd-7950-mac-edition
My rendering process is slow and OS X is having problems to refresh my monitor.
There is no HDR images included.
Where the problem is ?
First image shows GPU render time 6:20.
Second image shows CPU render time 3:37.
