That statement of yours is quite untrue. I've done similar
computations to Paul's, but less accurate. My computer (11th Gen
Intel(R) Core(TM) i5-1145G7) is considerably less capable than Paul's,
so I was aiming for general qualitative results rather than a
completely accurate simulation. My biggest compromise was to keep
all the planets in the same orbital plane. Implementing a completely
accurate orbital simulation would have slowed down my simulation by
a moderately large but still completely doable factor, had I wished
to tie up my only desktop computer for the necessary length of time.

longer step sizes for increased speed while maintaining accuracy.

I've attached my previous results, but as I've stated, Paul's are
more accurate. The point is, you can perform N-body orbital
simulations even using a laptop computer that is several generations
old.
