Hey guys. Started playing lotro again but now im on my lovely 5870s however i get worse performance with crossfire than with a single card? when i play windows with one card running its fine smoother average 100fps gaming. with 2 cards in fullscreen (same settings) its 50-60 fps but a total jerky laggfest as if im at 20fps.
Naturally this sucks and id like to be able to properly run with crossfire. what is wierd is msi afterburner shows one card running at 100% usage when in window mode. thats fine.
now in fullscreen mode card one runs at about 40-50% tops with gpu 2 running at like 70-80% whats up with that? if anything surly card 1 should be running the hardest?
oh also cat 10.12. i7 @4ghz 6gig ram win7 64bit
