The Falkenberg blog just prompted me to write on the subject, because it implies that if a creator exists, they are not omnipotent.

Seems like backward reasoning. It's fair to say "Hey, if the universe is a resource constrained simulation, that would explain why wave-particle duality!", but I don't see any logical requirement that "Because wave-particle duality, it must be a resource constrained simulation (if it's a simulation)".

Quite. The creator could just as easily choose such a physics for obscure aesthetic reasons, or reasons for which we have no concept at all. Furthermore, we have no way of knowing whether "resource constraints" are a meaningful concept outside our little physical universe, either.

"No one could be able to simukate our universe because we can't do it."

Other people think this way e.g. "The Earth's creation, according to Mormon scripture, was not ex nihilo, but organized from existing matter." If God did not create the earth out of nothing, but rather organized it from existing matter, it's not that much of a jump to assume that He doesn't run simulations with infinite memory either.
