one thing to be aware of, and I think this is a bug: Post render denoise is ON by default even though the box is not checked. You have to toggle the box on then back off again to turn it off. As of this moment I have not found the denoiser to be useful at all due to the way it destroys detail in the skin and makes the render look cartoonish or look like it's a Photoshop painting. Maybe they'll have controls for it soon so we can adjust how strong it works.
