They might be not ancient, but they still didn't manage to produce a good quality parallelized Vulkan renderer. Unreal made something (and marked the whole effort "archived"¹), but it's not really parallelized and performance is bad. I bet Godot will beat them to it, because they are focusing on Vulkan as their primary API.
