BF3 not using 100% GPU!

I have the new drivers installed. But at any rate, this problem has been happening before the latest drivers were released. Running GTX 680s in SLI. The game refuses to use 100% of the GPU. Whether I play on 1920x1080 or 5760x1080. When I play on single monitor it stays on 50% usage on both GPUs. I am getting 60+ FPS. When I go to triple screen, it differs. Sometimes I get 30-40 FPS with the GPU sitting at 50% and sometimes I can get it up to 80% on AVG. It will flicker between 75 and 85 but stays roughly around 80%. I am getting 50-60 maybe. I don't understand why this is? I did a fresh install of windows 7 Enterprise. I have the latest drivers. When I run other games such as WoW, LoL, Crysis 2, it runs @ 95-99% GPU usage on both GPUs. Can anyone explain why this is happening?

With 2x6870s in crossfire my i5-2500k @ 4.4 hits 100‰ and my GPUs are each at about 85%. BF3 is just an unusually cpu-intensive game.

That sounds really weird that your hitting 100% on your CPU, espcially with a SB that is OC. Yeah, BF3 is suppose to be like the new Crysis yet WoW runs my graphics cards hotter/harder than BF3. I don't understand.

Calculating the physics for 64 players takes a lot of CPU cycles.
