Here is a tweak using RadeonPro utility:

In “
The Black Death.trk” using
"very high" settings my FPS went up from
average: 20, max: 64 to
average: 42 / max: 122. All 4 GPUs are at about 75%.
The only issue encountered was some menu and mini-map (multi player) corruption. EDIT: Disabling API monitoring in RadeonPro setting resolved corruption issues.
Your experience may differ!
Here are the settings:
EDIT:
Different cards may require different settings.
I had issues with flickering using some of profiles. For those with flickering problems be sure to try different crossfire profiles. Remember DX9 cards may not work with DX10 profiles...
Also, try disabling API monitoring. This helped with menu corruption.
