Its like saying our universe is a simulation embedded in another universe. The simulation only need to be to the resolution of Plancks quantum of action. We couldnt distinguish any detail finer than that. The other universe could have a much finer resolution than our hbar. The simulator could be using a hundred grid points and time steps for grid point and time step in our universe.
