Since Substance Share https://share.substance3d.com is no more and what they have now does not allow uploading shaders, I will post it here and on twitter.
I highly recommend using Temporal Anti-Aliasing from Display settings view.
If there will be a demand for
anisotropy
I will add that later.
Allegorithmic are still using aged IS algorithm in their main shader that causes poor looking reflections.
I've updated the importance sampling to the state of the art random sampling and made temporal accumulation useful.
