If you want to achieve the highest quality and you can, use UE4 + ray tracing reflections.

Posts like this one is because I have created this comparison chart:

Unreal visual quality comparison chart between configs and UE versions

Hi all, After a lot of tests, published and read posts, I was wanting to publish a comparison chart between the most important features of different Unreal versions and configurations, in order to clarify to others (and even to myself) which systems or UE versions I consider the best ones to achieve the most visual stunning result for ArchViz projects (for other kind of projects, other fields could be considered too). What do you think? [unreal visual quality summary chart]
