Sure, but there's absolutely nothing to suggest that it will be some kind of deterministic computation underneath.

Not even. Even non-quantum clumps of matter are influenced by continuous fields and dilation effects from both special and relativity. Even without QM, our universe is not efficiently simulatable on our computational models because of general relativity.
