SLI is fine Smokey, actually the latest Nvidia Beta drivers have a profile for this game. Not sure how it plays without Vsync and a controller. It plays fine with Vsync on with the controller. Why would you play without V-Sync though? I am at a rock steady 60fps with 32xcsaa, 8xsupersample, 16xAF, Triple Buffering and V-Sync. I think I saw fraps hit 59 once, but other than that solid 60fps.
Also, the load times that had a bug with V-Sync seem to be gone. Load times are almost instant when going into/out of buildings.
Unfortunately, no improvements with the LOD/POP-In with the game. I kind of already knew it would not be improved, but if there is one thing taking away from the game it is the LOD/Pop-in issues. Mainly because it is so close to the characters view..but outside of that, it has been fucking fantastic. Like any game, there are things that are issues, but after 4 hours or so, I am really digging it.
Can you post your inspector settings? What compatibility mode are you using for AA? Does it interfere with the AA from the post-processing in the game?
