macOS / MBP 2017 with 560 GPU + WX 9100 + RX 580 eGPUs.
In RPR 2.0.10 the SSS options work perfectly except for one thing.
There is no difference between Random Walk and Christensen-Burley methods of SSS when using RPR 2.0.10.
I have attached finished final renders that compare RPR and Cycles side by side for the two SSS settings on an identical model.
The model file is also attached for your reference and investigation.
