You can also have a "block universe" in QM with the many-world
interpretation.  It has a more complicated geometric structure but
philosophically it is deterministic, with the same issues regarding
changes, free will, etc.

I believe QM is generally compatible with special relativity, but I am
not sure of the details.  A no-collapse formulation should be even more
compatible since you don't have messy and non-physical measurements to
worry about.
