I apologize. Re-reading this after my first cup of tea (note to self: must not post when still drowsy), I see now that I misread your post. Yeah, doing everything in a raytracer has its benefits.

Our GPU-based ray-traced 3D renderer is actually quite fast compared with anything that gives comparable visual results for these light-related characteristics. That said, the CPU-based renderer is slow, and we acknowledge that.
