What gives? I'm crossfiring Radeon HD5770's and it doesn't feel like FFXIV is giving a hoot about it. Feels like I'm running a single card when I'm in game. Does this game not support crossfired cards?

Running the latest 11.3 CCC drivers, here's the rest of the rig:

AMD 955 @ 3.6ghz
8gb DDR3 Ram
Radeon HD5770 x2 (Crossfire)
OS: Windows 7 Ultimate
