Then you're not doing something right. AFR (Alternate Frame Rendering) means that one card will draw even frames while one card will draw odd frame. Some games do this by splitting the screen in 1/2, others by drawing certain aspects while the other card handles the rest. Obviously, without a real profile for IL2COD it's not scaling to it's full potential. It is indeed scaling though, and I get a 10FPS average increase on the black death track on max gfx settings with this setup. I've also gone from 50ish with one card to 80-100 FPS online with SLI on. If AFR is enabled you will never have a situation where one card is doing 100% and another 10%. With AFR enabled both cards should output almost equally. Mine stay around 70% usage.
It's only when I use Nvidia's recommended SLI settings (not the settings I said to use) that one card does 100% and the other 10%.
