If you are having very bad load times (30+ minutes or similar), try this:
turn off your network
start the game
wait until you see the screen that network is needed
turn on network
enjoy
I observed that the intro video does not play smooth with this method, and who cares, but this may be a tip to the Asobo team what conflicts with the smooth load process on some computers
UPDATE : after the Dec 11 program update, at least on my side, the workarounds were not needed (IPV6 or network off/on methods). Hope that many of you also see an improvement,
