I didn't say that I like new renders more!.. although if i think about it, yes, I like them more - as they are of higher quality in terms of rendering detail!
But there is no need to raise this question! The old "render" is gone, why raise the issue of realism, I do not understand! Really he did a lot of work in terms of new rendering. Yes, I do not argue if you use light correctly, you can achieve better quality, etc.
There are light settings such that they make any picture like a real photo, but we don’t know what resources and knowledge the new "renderer" has.
It's just that if many people ask to change the new renders to more realistic ones, then the update will take even more time!
