Thank you for your fast reply Warp, about the caustics seems i was too fast to
ask, had not reached that part of documentation yet.

Now, if i don't sound too bothering, i would like to ask 'why' on those two big
NO's ( about GPGPU and about AA on the GPU ), if that's not a huge explanation
of course.

Thanks in advance

E.T.
