How does a finite speed of causality help simulation performance? You still end up computing the interaction of every event with every particle in the Universe. Despite being amortized, you still need to compute the same number of interactions per unit time.

Finite speed of causality helps scale the compute across multiple servers.

If you have an infinite speed of causality, a server may need to receive data from all the servers. In the worst case, all servers will need to receive data from all the servers.

With finite speed of causality, a server only needs to receive data from the servers that simulate parts of the world that are nearby.
