my system has an i7 pro with an ati 5970 (2gb dual gpu)
arma 2 after recent offical patch now runs a dream
to my surprise OA runs very badly ( just like arma 2 when it was released)
I've decided to not play it untill proper patches come out to address the
problems -as i refuse to spend time constantly fiddling around with it
will use arma 2 now that runs well ( & now has crossfire support etc )
( did try to renam OA,exe with arma2.exe etc -it did use crossfire but with no performance increase so wast of time for me )-: )
I'm fairly sure OA will be sorted as arma2 was -the sooner the better as I've already paid for it !
