simple fix is to change bit code from 0x4005 to 0x4205, i hope to see proper SLI support soon !

SLI has worked just fine after patch 1.3. At least for me.

With the last 280.19 beta drivers, SLI support is awesome. I have 2 x GTX 580 cards and SLI scales like crazy (always above 90% usage, verified with eVGA Precision). So I would say "Problem fixed" for this issue. Update drivers instead of always finding hacks to make things work.

Sli is working Very good here.Gpu usage hovers around 97 percent on my 3gig 580 tri sli.I am using 1.3 patch and 270.61 drivers.2560x1600 with uber I get anywhere from 80 to 130 fps in combat.

Yep. SLI is working for me too. 280.19 Nvidia beta drivers installed.

For those who have SLI, i think they need to disable vertical-sync.

Patch 1.3 nearly doubled my fps with SLI and I'm using old drivers!

Anyone running SLI with 3 monitors? How is it performing?

[digitalrurouni]

I gotta check out the load balancing on my sli set up at home. I am on 285 OC edition video cards and though I am playing at 2560 x 1600 the game is very smooth everything maxed out with tweaked user.ini settings. There are some battles where the frame rate lagged big time but still it's amazing to see how good these cards have lasted me. I think its time i bit the bullet and got me a pair of them MSI lightning vid cards!

or you can do what i did buy pair life time Warranty set eVGA GTX 480+ AR

Disabling VSync is a waste of resources for powerful configurations. Anything above the refresh of the monitor is wasted energy / load.

confirm patch 1.3 properly loads both GTS450 on 100% using 280.19 drivers. although I won't roll back to 275.77 just to prove the point
tested with EVGA Precision
