Anyway, it doesn't seem to be anything like consistent in terms of what the specific problem is that's causing the bottleneck; other than the fact that it seems to be at its absolute worst with the Batmobile being on screen. I've seen people complaining that its lagging badly for them when they've got a Titan X card which is just absurd. I'm actually really curious to see where the hell the bottleneck is on it out of simple morbid curiosity, its got to be an optimisation issue.
One thing I've seen a few people citing, however, is that they don't have issues with 9xx Nvidia cards (most of the people I've seen saying it runs fine seem to claim to have these cards). Which leads to the possibility that the ONLY type of card they've bothered to optimise it for is the 9xx cards. Which was an unbelievably silly move if true. Not to mention the apparently downscaling of the PC version.
Classic example of "why you shouldn't preorder".
