That's neither ironic, nor does it make the engine too good. It just means that the designers did not notice this flaw
in the engine and did not act in it, resulting in sub-optimal frame rates for end-users.
If the engine had, by its own diagnostics, noticed that it was loading area renders before they are needed, and adjusted those accordingly, that would be an engine that is too good.
