Perhaps - but that sim is the universe itself.
A real sim would have to be housed in a computer with the tiniest portion of the universe's computing power. The number of bits of state in the "universe simulation" is about 10^120. A common computer today has a memory capacity of about 10^10 bits. The biggest computer isn't enough to simulate one person.
So, if I am in an artificial simulation, likely I'm the only real person that exists. Everything else is an illusion, created on-demand (it takes too many resources to create you lot for real). I would guess any "glitches" get wiped from my mind real-time so I don't notice them. And if I'm in a sim inside a sim inside a sim, well -- with each level having exponentially less complexity, I must be a complete idiot with only a few bits of simulation.
On the plus side it must mean I'm immortal (until some programmer installs an upgrade). I can totally ignore your comments now, non-real people!
Not if the universal simulation employ the same strategy of creating illusions on demand for your benefit.
It seems to me it would quite easy for a simulation to avoid giving any evidence of granularity or other indications of How it is constructed to the denizens of the simulation. One may say the purpose of the simulation is not to give particular illusion to its denizens. Therefore the denizens are not precluded from seeing evidence of how the simulations are constructed due to the indifference of the designers. That still leaves the question of what is the simulation simulating?
