In the link are some of the reasons Godot might not be ready for your 3D game (it’s a performance analysis of a third-person shooter demo someone made in Godot)
Godot will only ever get a slice of the low end indie market in the 3D space. There are tons of productions that cannot afford to make use of a lot of even moderately advanced engine features because it takes too much effort to generate content of that quality. These are also the kind of productions that are consistently ignored by gamers.
Becomomg a good 3D engine means putting a lot of effort into tooling and the related infrastructure. The runtime part of that is actually minor.
Its quite exciting. I used godot shortly after it became an open source project in 2016 I think. It was cool back then but I never saw any good 3D games built with it. These days I don't do game dev anymore but I'm still impressed with how much progress they have made.
