Playing Tomb Raider in CF is beyond phenomenal, even if i include TressFX. Playing Battlefield 4 in CF is beyond phenomenal.

Unfortunately, i need to disable CF when i play Watchdogs...

Just my luck, i bought 2 cards and i only use 1 for Watchdogs...because it cant freaking run it on both...

Why?
