Not enough to make even moderately latency-sensitive gaming worthwhile, though. I don't see that getting better unless there's widespread building of data centers all over the place to keep the services right in your neighborhood.
I wouldn’t play really competitive shooters that way but it’s low enough to not bother me even in mouse/keyboard FPS (for the PC services). For controllers it’s completely negligible, like playing with a Bluetooth device or on a 2015 TV.
That said, I’m in Santa Clara County near one of the major Shadow datacenters, probably the others too, and I have gigabit. I am in the ideal situation you describe.
So is a lot of the world though. US is super rural for its economic weight but that’s not the norm. Most developed countries have much higher density and better networks. I think we’ll probably just end up dragging behind the curve until we mesh the flyover states better.
