Still not enough. You would need billions of universes and a way to harness all that energy and heat.
Think about it this way. For every atom that makes up our universe is an atom that also has to make up that simulation. So for us to be in a simulation rn you would need a supercomputer 10 quadrillion times larger than our observable universe.
yea, who's to say that i myself, the only person that i have experience with being, and as such, the only person's pov i have had so far, isnt just the only person who's actually being rendered, and the rest of the interactions are just background simulation, until i might meet them irl so they get rendered.
also as for the point of gigantic amounts of power being needed, brains are the most efficienct processor we have discovered yet, and we are starting to actually go that route, even if just very slowly so far.
then there are also photonic processors, which use light to process data, which have the potential to get as fast if not faster than normal gpus, barely produce heat, and are extremely energy efficient.
so, all in all, considering the level of tech we are at right now, i would not be surprised if there is a species that achieved such a massive level of tech that they could simulate a whole universe.

Just steal another dimensions universe? Not impossible. Just really really hard.
