[Bf-cycles] Cucles rendering speed difference between preview viewport and final rendering

[Brecht Van Lommel]

For rendering fairly simple images there's a CPU bottleneck with F12
rendering, for viewport everything stays on the GPU. It will be
addressed in one of the following weeks, it needs some bigger changes.
Background render from the command line does not suffer from the issue
as far as I know, that's the only work around I can suggest now.
