The thread title pretty much says it all. I've already played thru the entire game before I realized crossfire wasn't working. One 7950 gave me playable frame rates at 5760x1080. (High Settings with 2xaa I think). I started up MSI afterburner on my fourth screen though and notice that while playing my second GPU is at idle. Anyone know how I can get crossfire working in the game. It works well for the other games I've played lately (verified working in sleeping Dogs, Battlefield 3 etc...). I'm running 2x Sapphire 7950's (One OC edition, one Boost Edition). I was using Catalyst Beta 13.2.6 but upgraded today to 13.2.7. Still no change, second GPU sits at idle when I play Crysis 3. Any suggestions?
