I have dual AMD Radeon 7770 Sapphire that I am using in a CrossFire setup. When I play the game normally, the two cards share the load perfectly fine and I can keep my graphics all the way up without issue 99.9% of the time.
My problem comes when I turn on my streaming software. When I turn the software on, even if I am already running my game with the dual cards, the system grabs onto the main card (happens to be considered slot 0) and doesn't use the other card at all. So, my 55% on each card, shared load, turns into 100% + video encoding on one card. Is there a setting, maybe in the streaming software, maybe with the card, that would keep the load spread on both cards?
