Crimson Desert's engine is heavily derived from Black Desert's engine (called BlackSpace Engine) so it wasn't really from the ground up, but your point still stands.
I've read somewhere they had several attempts until they could comfortably support the scale of the game, so maybe it was just rebuilding some major parts
