It would indeed be falsifiable. Remember, QM predicts that the universe is filled with quantum foam on the order of Planck scale, and also predicts that interactions can operate over any distance (although information itself cannot move faster than light).
This is, essentially, not computable on any architecture whatsoever. You'd have to have simplifications. And that means GR and QM cannot be unified if we live in a simulation. GR would be a deliberate simplification to avoid having to do an impossible number of calculations. It would be roughly right, but measurably different.
You also have to have quantised spacetime, as no technology (however advanced) can describe infinite precision.
Simulation can be event-based or time-based. Since there seem to be valid reasons for thinking objective reality is a very dodgy concept between quantum observations - we can calculate outcomes but not paths to get there, the numbers don't work if you try to do intermediate calculations - then I would contend physics as we understand it could only be done via an event-driven model. But if this is true, then it would be necessary that this be true for ALL of physics at this level. The simulation would need to be consistent for everything modelled, but physics has no such constraint.
Time is thought to emerge from particle interactions, and particles are thought to emerge from field interactions. By implication, fields can't be constrained by any restriction on time. If fields are event-driven, then I might get interested.
