When you code an application SLI/crossfire doesn't "just work". You have to specifically use the right API's in the proper way to enable scaling. If this hasn't been done (which I don't think it has) crossfire/SLI will not work. When I say will not work what I mean is that when you enable it you will see no performance increase and often a performance decrease (due to the extra overhead of the additional card) I would expect once the initial madness has died down we'll see a patch later which adds support. You often see development teams with home-grown graphics engines have this problem. That's why when folks run crossfire/SLI benchmarks they use the well known engines to test (frostbite, ego etc.) The reason is literally thousands of hours have been spent optimizing the engines to work well with crossfire/SLI.
