ati crossfire

[Stew U-582]

Hi Guys,

Im running the latest version of catalyist controll centre
to controll my graphics options. I have two Radeon Ati HD5750 1 gig cards
in crossfire mode. ive noticed when I run sh5 only one of the cards
is taking the work load. Ive tried running other games with exactly the
same settings and both cards share the load , as they should. Does
anybody know any reason why this would happen only with sh5 ?

thanks
