I don’t think there’s many three body problems in the real world where compute is the limiting factor. If you’re projecting so far out into the future that simulation speed is a problem, you’re initial measurement error will have compounded to the point that your solution is meaningless.

We struggle to predict the exact path of asteroids because of measurement errors, not because computing is slow. Minuscule changes to the initial condition manifest as massive differences in the outcome.
