I think free will vs deterministic physics is a false dichotomy.

My instinct is that physics is performing a computation at optimal efficiency. Even if everything is deterministic, there is no other way to determine the outcome other than letting it play out.

In other words, even if a decision you made was bound to happen, there was no other way to find out what that decision would be beside letting you compute it.

So, your decisions can be both deterministic and unpredictable.

From this perspective, I don't think the existence or absence of randomness makes any difference on the question of free will.

Lets assume determinism is epistemological unfeasible, ie not possible to evaluate all the states due to limitations. Unpredictability makes no difference to the ontological question of whether actions are due to casual chain or pure irreducible randomness (if it exists in fundamental level). There is no other alternative. Free will is ill defined/semantic nonsense in libertarian sense of its use as there are only two possibilities.
