Crossfire only using 30 graphic card resources?

Up until now ive played at medium setting and been getting a steady 60-70fps
at these settings. So I thought id up the gfx-settings abit.

Now, heres my problem. As soon as I set the shadows to medium or high
the fps drops to 40-45fps.
I'm thinking my cards should perform better than this, so I check their usage
and find that they are maxing out at 35-40% usage only.

So, why is this? Surely a dual HD5850 setup should be able to run this game at
high settings?

It seems im not getting any benefits from the crossfire setup. If I disable crossfire
and run the game on only one card, im getting the exact same performance figures
(ie 60fps on low shadow, 40fps on high).
The only difference is that with only one card the game uses 60% GPU resources.

(Oh, and im using catalyst 10.4 btw)

    There are many many posts on how ATI cards seem to not be functioning correctly with STO, in my opinion I think it is a driver issue as NVIDIA users have not been having these issue.

    Yes there are, but i have found none with this specific issue while searching.
    Most of the are about stability issues - which I'm not having.

    Facts are all that matters, not opinions (no offense).
    This could very well be a STO specific issue.
