SUMMARY. A low-level physics simulation using the simplest simulation methods, which simulated our universe on a grid with finite resolution, would result in some potentially observable distortions of the simulated physics because of the rotational symmertry breaking effects of the simulation lattice. I would think that even the earlist simulations of systems sufficiently complex to contain observers would make use of powerful computational shortcuts that would eliminate the opportunity to observe any such discrepancies (mostly the simulation would take place at a much higher level of abstraction in order to reduce the computational demands).
One reaction to these apparent enormous coincidences is to see them as substantiating the theistic claim that the Universe has been created by a personal God and as offering the material for a properly restrained theistic argument—hence the fine-tuning argument. It's as if there are a large number of dials that have to be tuned to within extremely narrow limits for life to be possible in our Universe. It is extremely unlikely that this should happen by chance, but much more likely that this should happen, if there is such a person as God.
