Luthier-Will SLI be fixed in the patch?

From 25-30 FPS to 50-60 FPS is a 100% increase in FPS...
As far as I know, Luthier expected an increase of "ONLY" 50% in FPS and 50% of 25-30 FPS would be ca 12,5-15 FPS more compared to what you have now ... So after the patch you should be looking at 35-45 FPS AT BEST!.. Still significant though!!

Just saying!

For what I can judge the SLI for two GeForce gfx580 1.5go ddr5 works without any problem. It is what I have in my PC.

My GTX590 is two 1.5 GB 580's on one card. It looks like both GPUs are running full bore when viewed in the control tool. Nevertheless, this card is slower in Clod than my single GPU 3 GB GTX580. IN SLI both GPUs are processing the same data so no benefit.

However, two GTX 580's SLI beat a 590 by 15-20%. It actually has a tough time beating 2 GTX 570's. I believe the GTX 590 is underclocked at about the same as a GTX 480 for heat issues, which is why it is so quiet.

Working SLI in CoD would make a fair difference to the 590 because you cannot turn off SLI.

Agreed
I'm not certain whether the clock speed or the memory is the biggest contributor.

SKUD,
In Sli you don't double the ram of one card unfortunately, so your 590 (2x580's on one card @ 1.5gb V/ram) shouldn't give 3gb of ram only 1.5gb. The 580 with 3gb therefore is the reason of better performance. We will have to wait and see if the patch is going to address the V/ram issue. I have 2x1gb cards in Sli and both are working to full capacity indicated by my precision tool. I think at the moment V/ram or lack of it is some of the reason that those of us with 1gb are noticing more problems than those with 1.5gb or more. My frame rates are very good but the stutters down low are a pain.

Again agreed.
I believe if my 590 had 6GB (3GB each GPU) and same clock speed as my 580 it would get equal performance. Now the second GPU and the 1.5GB of memory it has is wasted. 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.
