Obviously, Crossfire has some performance issues with F.E.A.R. Although on average we see an increase in frame rates, we also notice much lower minimum fps - 26 to 28 fps compared to 31 fps we saw with single card setups. Gameplay testing sessions confirms that Crossfire has trouble with some parts of the game. The frame rates near the checkpoint in the Afterimage level (between ATC and Replica forces with mobile armor) are very much unplayable.

Click at the detailed graph and you'll see see the problem lies near the end of the performance point - the explosion on the last room. As we have said repeatedly, minimum frame rates when you play the game tend to be much lower than what you saw in F.E.A.R Performance Test. You'll want minimum frame rates around 35 to 40 fps for a fluid gameplay experience. A Crossfire setup is unable to deliver such experience, though a single card setup can. Obviously, AMD have issues to sort out with Crossfire and F.E.A.R.
