What happened to Scrambling Distance? It´s been used in Theory and it will help speed up rendering

Thanks! If you can do both, GPU only and CPU only

And do some with 200 samples instead of 500 too, to compare noise levels at low sampling (at scrambling 0.02 may look bad with just 100 or 200 samples)

Thanks!
