Your option 1 seems to make a false distinction that something non-computational could exist

William Rapaport, in the paper PhilGoetz refers to, appears to exclude the idea that the universe is performing computation.

He states:

... it could also be said that it is Kepler’ s laws that are computable and that describe the behaviour of the solar system, yet the solar system does not compute them, i.e. the behaviour of the solar system is not a computation, even though its behaviour is computable.

I would agree with you, that the universe is performing computation.
