I have severe doubts that a simulation of the fidelity we observe in our existence is practical to build in our universe.
It certainly isn't. You can't simulate three atoms using two atoms. There's no reason another universe has to abide by the same rules as ours, though. It's not something anybody should actually worry about but it's about as scientific an idea as string theory is.

That's not necessarily a ringing endorsement ;)
At least string theory has lead to some very powerful and productive mathematical techniques, if little in the way of actual physics.
If we can invoke other universes, then we're kissing Occam's razor goodbye and we're in magical fairy land territory.
I’d go further and say they require such a being, despite us having reason to believe such a being is not compatible with our understanding of how the universe actually works.
Just as the existence of an all powerful eternal being doesn’t seem compatible with what we know about what’s possible in the universe, I have severe doubts that a simulation of the fidelity we observe in our existence is practical to build in our universe.
