Despite the challenges using it in a tree, and the contentious issue of whether light playouts can make a really strong program, I think this is interesting research. By 1.6 times quicker than libego, do you mean as it runs on the CPU? Or is this a simulated speed as if it was running on the GPU? I think libego was the clear leader in light playout speed, so working out a way to do playouts even faster (if that is what you have done) is amazing.
