Don't knock Sli people until you have tried it. It works fine with most sims, this is the only one that I play that stutters. If you look at some of the posts others that have only one card are having the same problems that Sli gets blamed for. I've 2 x gts 450's (don't laugh) in Sli and have good frame rates (single play London Attack 40--60fps and over water in other single missions up to 90fps). My son has a single 560ti and doesn't get those frame rates or as smooth, he's even shelved CoD until there's been some major improvement. I've found that it's the ground rendering that seems to be the problem, once I'm up over 3000 mtrs there's no noticeable stuttering. Guess that is the hight limit for missions, during the WW2 citizens said that a lot of combat was not visable from the ground just the trails of aircraft.
