Whoever is running the simulation cares about whether we're looking. They had a good reason for going with quantum mechanics rather than something that would be easier to simulate.
The power running the Universe doesn't have infinite CPU/GPU/RAM resources at their disposal, any more than a game developer at this level of reality does. Some optimizations (or hacks, to be less charitable) are necessary. Quantum behavior is one of those hacks, part of the code that manages the potentially-visible set. It would be wasteful to render or run physics on particles that nothing is interacting with.
The only questions are whether God is an Nvidia fanboy or an AMD die-hard, and if He signed an exclusive deal with Sony or Nintendo at some point in the future.
