If we are simulated, it'd be interesting to know how optimized the simulation is. Maybe the simulation is reminiscent of The Matrix in that reality is essentially an elegant artificial abstraction that acts as glue tying together the perceptions of each simulation participant. Perhaps a proper, low-level simulation isn't computationally prohibitive, but simulating the rest of our universe is. In that case, the cosmos itself may be an illusion despite an otherwise interference-free simulation. Or, perhaps the entire cosmos is simulated just as we are—including the hundreds of billions of galaxies present in the observable universe. This would heavily imply that computational resources are not finite. I'd argue that regardless of whether we're in a simulation or not, the sheer vastness of the observable universe heavily suggests that space may in fact be infinite—which by extension creates the potential for simulations to exist at grand—or even infinite—scales.
