I remember an interview where one of the lead devs mentioned UE5 needs to be optimized as you go.

Apparently, you can’t just build first and hope to optimize everything later. It becomes far to complex to do it that way, and that’s the way most studios are used to working. They often even have two seperate teams and seperate development phases.

So it’s a little encouraging that they’ve changed their workflow to prioritize optimization and engine efficiency.
