For people who think this universe is a simulation, maybe the simulation is possible because the next universe up has more dimensions. (Maybe the 20+ dimensions some string theorists talk about.) Despite Flatland, you can't really do much in 2D; the connectivity is too limited. 3D is a minimum for life.
Computing would work better in a higher dimensional space. Propagation delay is less of a problem because you can have more things closer to each other. Cooling would be easier with an extra dimension or two into which heat could be radiated.
But if higher dimensional beings want to run a universe simulation, 3D would be enough for entertainment purposes.
