The latest DS betas have a new parameter in Render Optimization -> Guided Sampling

Here are examples (all rendered 3 min on RTX 2070 notebook):

Guided off, Caustics off

Guided on, Caustics off

Guided off, Caustics on

    Caustics on wins for realism but Guided On gets close.

    The blog post by the Iray dev indicates guided sampling can speed up some renders. https://blog.irayrender.com/post/670028436722647040/iray-202110-beta-part-ii

    Anyone done any time testing for scenes yet?

    I've tried with both on and it's not too bad. Not a speed demon, but I have a decent card so mileage may vary. The image also has spectral rendering turned on as well. Took about 20 minutes.
