youtube is your friend, or any activities that can sidetrack you from waiting patch to finish. lol

Another tip is to backup your installed game data, and when you install on fresh new pc/OS upgrade, install the game then copy paste your backup to it. There's still patching, but it'll be much quicker. Have done this myself alot times, especially during returning campaign and it sure's save alot of times since I'm updating across 2 desktop PC & laptop.
