Understanding DMC Sampler

I think that in V-Ray 3.0 it can be very simple. You focus only on AA and min shading rate settings for very good quality and fast render times with minimum setup time.

For most of scenes that require a lot of AA samples (DOF, motion blur, a lot non-glossy reflections, small geometry details) it would be something like this:

AA sampling adaptive/progressive 1/16 to 1/25 with with min shading rate something between 2-10 (I find that in most of my recent cases 6 worked best).

For more simple scenes, like studio renders of products, most of the visualizations I think that something between 1/6 - 1/8 would work best with min shading rate at 16-32. It would focus less on AA, more on shading for lights, GI (if brute force) and glossy materials.

In both cases you control the quality with noise threshold.

I agree with this - the new Min Shading Rate parameter is a VERY powerful new addition.
