Star Wars Battlefront SLI Problem

I-7 4770k 3.5 Ghz

2 GTX 760's

12 GB of DDR3 Ram

So I have a problem where battlefront won't use both graphics cards to run the game, only uses 1. One card is around 80 c and the other one is 40-60 c. I have had this problem since the game came out. I also have the latest NVIDIA drivers.
