I am trying figure out why when i play multiplayer my frames drop off so much. When I play the showcases, the game runs between 30-60 consistently on the lowest possible settings. When I jump into multiplayer on the same settings, I am lucky if I even get about 15-20. Also Is there no optimization for SLI? I have 2x GTX 460 1GB Fermi's in SLI configuration and I messed with the Nvidia control panel for the SLI in game. There is no performance difference between using a single GPU and SLI being enabled. I heard my cards together are equivalent to about 10% better performance than a 480. Should I be getting better performance on my current settings?
