You cant yet, maybe if they release a patch. As for Vsync, if you turn it off in game you can just force it from the control panel and you'll get 60fps instead of 30fps. Also anyone with a 120hz screen can use Nvidia inspector and change the Fable 3 profile so that the game will use highest refresh rate possible and you can get 120fps Vsync. That is if it runs well enough for you. A single 580 or 3 in SLI and it still generally runs like turd for me. Very impressed with the game so far though. I completed the game and started a 2nd play through right away. For a game i was wanting to hate it was pretty damn good imho. Its a real case of haters gonna hate because its far better than some people have been saying.
