This morning after I've got game dnloaded over night I tried for short time before work and crossfire was working fine, both cards usage were normal.
But now I have no idea why but it isn't working any more.
No matter what kind of setup I change in options as soon as game start. .that handing the gun part in game, second card usage drops to 0.
In small window before that when it is loading there is some small usage and then right after game start second card just drops to 0 and it is not used at all.
Doesn't work nor with 1 monitor nor with 3 monitor eyefinity setup.
I had latest beta 5 drivers first, then tried updating to beta 6 ati drivers.. no luck.
Any idea why my crossfire died in Crysis?
It is full screen on, and btw in couple other games everything works perfectly fine, only in Crysis nothing
help?

I have to alt tab out and then go back into the game every time I load it to get corssfire to work. And when I say work I mean anywhere between 60-80% gpu useage. Seems to be pot luck and I can't get my 120fps!!!

Can you post your system specs and driver version? That would help us help you.
