Luthier-Will SLI be fixed in the patch?

My precision tool also says both GPUs are going at it full bore. Trouble is I don't think they are splitting the work load, only doubling it. I believe SLI works by splitting the data stream sending half to each GPU and then recombining by interleaving the data after they have processed it. If the software isn't controlling that then both processors get all the data. Someone correct me if my perception is wrong.

I have 2x GTX 580 3gb (disabled SLI for CoD). I never come close to using the 3 Gb with CoD and I use 2650 x 1600 res on an SSD (helped slightly but not much). I believe just over 2 Gb vRAM is the max I have ever used. My GPU and CPU are never maxed out, and my RAM is never maxed out but the stutters are really a problem especially low or over cities. Proof the stutters are not from a lack of resources at least on my rig.
