Notice how all three of the games at the bottom of the list on the posted graph are all physX games? This is why
Except Metro 2033 is pretty high on that list and it uses physx pretty extensively.

2) When you don't use a *dedicated* physX card in Mafia 2, the cloth physX runs on the CPU, which drags FPS down pretty considerably... basically it can cause bottlenecking.

If you really want Mafia 2 to run well at the highest settings + physX, you really want a dedicated physX card, not to be running physX on your rendering cards (in this case your SLI set). That, or skip the PhysX entirely, which should (as the graph posted shows) give you much better SLI scaling.

I have seen instances though where forcing the physX to run on card 2 (bottom card) in the SLI set results in slightly better fps than leaving it on 'auto' or card 1. Worth a try.


This.

Also lol at people getting mad because a guy with $400 in video cards is only seeing $210 worth of performance.

Don't offer suggestions that aren't well thought out (he clearly was already running the hack) and you won't get snapped on.
