God you've gone from a somewhat reputable source of information about the game to a moronic doomsayer that is exaggerating to join the circle jerk.
I don't doubt this is going to be a rocky launch, but it isn't going to be as bad as you just suggested.
Sorry about that, been a hell of a day.
My friend acquired a leak copy. It's more than likely patches will be avaliable on release but his comments state that the game is not running at a consistent framerate. It dips to 1FPS (counter) in many places. There doesn't even seem to be consistency within the framedrops, except that they happen outside.
Seems to be related to a CPU bottleneck which has exists in many, many Ubisoft titles.
