How? Does good frame relay switches accelerate photons or something?

Yes, both frame relay and ATM give the "appearance" of a 'no-hop' backbone.
Just because traceroute doesn't show the switch hop in the middle doesn't mean
that they aren't there.
So what is inherently better about that, unless you are into marketing
vapours?
I can see the argument that with current generation of rather deficient
routers, switches have smaller per-hop latency, but even this is pretty silly
since that difference is a noise lost in the cross continental/cross oceanic
propagation delay.
This should be a moot point any way with the impending introduction of real
routers in to the networks.
