I play quite a bit of Insurgency. Unfortunately, I've found the frame rate and "play-ability" is much improved when I disconnect the power to the second video card (both are Radeon R290x Sapphire 8GB). Insurgency is, again unfortunately, not one of the games specifically optimized for Radeon Crimson. I would rather just disable crossfire in the crimson control panel (which was an option in Catalyst) versus shutting down my pc and unplugging power cables...etc... Thanks.
