Shader compilation is slow and do not use available ressources

Once your project is big, you’ll also want to take a look at: Derived Data Cache | Unreal Engine Documentation

I mean, this very documentation page says that there isn’t supposed to be an initial compile (it’s under DDC Pak, for the curious), and, indeed, in some cases there isn’t. It’s not consistent behavior, though.
