This depends on the user. Personally I never minded the extra frame of latency.
And some of the newer Gnome desktops have even removed that, thanks to some tricky work by one guy, as I understand it.
I may have misunderstood the explanation but it seems to involve some nice timing getting all of the application buffers swapped just before the main GPU screen buffer swap. This gives applications long enough to draw updates, for the most part, and gets all updates into the next screen buffer update instead of the update after that.
