I seem to recall reading that some calculations complexity were dramatically reduced with a new method having something to do with volumes of n-dimensional polyhedra. Can't find it with google because I don't recall enough.

Maybe you are thinking of the amplituhedron [1] which can make calculations of interaction amplitudes much easier than summing up a large number Feynman diagram.

That's it I think. No infinite nesting of diagrams for virtual particles.
