ALT-TAB disables Crossfire
I normally get good Crossfire performance in CloD (including the Steam release (1.02) and the current beta 2 patch (15866) with core patch (1.04).
However, if I ALT-TAB out of the game, and then return to it, Crossfire is functionally disabled with fps dropping by half and utilization of the second card showing a drop... see attached images. I don't have this experience in any other games or applications. The only way I have found to remedy this is to restart Windows... restarting the game does not help.

Smurf...how are you forcing your cards to run at 99%? Mine are only showing at like 50% or less.

Well... I'm not doing anything special I know of. The difference may be the video cards you have, your CPU and/or the video settings you are using.
I'm using maxed out video settings with a resolution of 1920x1080 and, by today's standards, rather weak HD5850s. If you have newer and better cards (6950, 6970, etc) and/or are running lower video settings you may not be pushing your cards. Also, I have noticed what I believe to be my CPU (or maybe RAM) bottle-necking things (when lots of activity, lots of other planes in the air) as my framerates will drop and at the same time my GPU utilization will also drop (which I presume to be because the CPU is not delivering fast enough).

Smurf...I am running dual ATI Sapphire 9870's, with a 6 core- AMD 1100 BE overclocked to 4.0 and 16 gig of 1600 Corsair Vengence ram. So tehre is no way to force the GPU to a higher level huh?

Not that I know of... you could try messing with the 3D Application Settings under Gaming in the AMD Catalyst Control Center (if you installed it with your video card driver), you might find a setting that is affecting performance.
What resolution are you at?
