Ok, I ran those tests on a machine with an AMD FX 8350 CPU and an NVIDIA
GTX TITAN GPU.
Results attached. It's up to 2x faster on the GPU than the CPU but the
speedup is less interesting in goliath.g, because of the depth complexity
of the scene I think.
We basically need to do a breadth-first rather than a depth-first ray tree
traversal like the ANSI C code in trunk/ does if we want to have improved
render performance in these high depth complexity scenes.
