I'm getting bad scaling in most games after adding a second EVGA GTX560ti Superclocked. In games like COD4, Portal 2, BFBC2, and Mafia II, my performance is great. I get almost perfect scaling in those. However, in games like L4D and BF3, I get very low usage of each card, and my framerate either does not improve (L4D), or drops considerably (BF3). I understand BF3 has had problems with SLI, but L4D? Across the board however, I'm not getting a consistent usage. In Cod4, my usage sometimes drops between 80% and 60%, with my FPS going down to about 190.
