By scaling I mean how much extra performance is gained by adding 100% extra (one more) graphics cards. SLI is unusually bad in metro. This explains why reviewers are complaining about GTX 590 performing well in some games, but bad in others like metro. The SLI scaling is bad.

Look at the anandtech numbers yourself. GTX 580 beats 6970 in metro. But when you SLI it, it loses.

CONCLUSION: SLI SCALING = BAD IN METRO AND STALKER
Correct me if i am wrong but it smells Vramlimit as hardwarecanuck show over 82% and metro2033 uses over 1,4GB in 2560x1600 with light settings and anand uses more AA right? so if they used the 3GB in reviews it would be more interesting as the limit would not be a factor that can impact to mutch even on highest setting as Metor dont uses 3GB in 2560x1600.
