Certainly. Of course it can never have a perfectly detailed model of my
environment, which leads me to wonder if perfect simulation is ever
possible. If quantum mechanics interacts at any level with classical
mechanics, it would be impossible for even a quantum machine to simulate a
physical environment of similar size to an arbitrarily high degree of
precision. As you say though, a 'very detailed' model is certainly possible.

And of course we are possibly interacting in a simulation at this very
moment as well. This in fact would require less processing power than a
perfect simulation as only the physics of what is immediately observable and
causally interactive with me would need to be simulated. I would probably
not notice a difference if some of the quantum interactions get
'approximated'. Of course, under such a scenario, science in a simulation
would hit a complexity wall at a specific scale of observation.

Assuming there are no barriers of which we have no conception yet, yes.
