Everything on uber high, vsync on application settings and nvidia custom set 16x AF 4xAA 4xSuperSample

2xGTX580

Enabled Aero desktop theme for vsync to work correctly.

I figure this hotfix has nothing to do with getting SLI/Xfire to work correctly but just to allow us to run the game when the bridge is enabled and/or allow people with permanent internally enabled SLI/Xfire to run the game.

I think it has something to do with SLI. But i hope its the lacking profile that still keeps from using SLI.
My Summary:

SLI works and gives good performancegain with AFR2 enabled.

SLI Produces INSANE visual tearing.

Visual tearing appears WITH (AFR2) or WITHOUT (FORCE SINGLE) SLI being activated in a manual set up profile.
In order to avoid visual tearing i have to deactivate SLI in the driver itself.

The selected Vsync setting in driverprofile DOES affect Framerate. Thus i get over 100 frames and tearing with AFR2 on and Vsync OFF and 60 Frames with AFR2 on and VSync ON.

Another thing i noted is that clod no longer stretches the picture the the monitorsize. When running 2560x1600 native monitor resolution i get black borders on all sides of the picture when i run the game in 1920x1200 resolution fullscreen set to ON.
So i have to lower desktopresolution to match ingameresolution if i want to avoud playing on something that looks like a postage stamp

Single GPU performance is OK.

PS: Oh and the driver i am using is the newest 306.63
