Mafia 2 Livestream & Physx Tweaks

So finally got this thing running smoothly.  Not sure if the fix is out, but you can fix the Physx problems by uninstalling and reinstalling the Physx drivers that come with the game.  Once you do that I suggest doing the Physx tweaks from this site - http://physxinfo.com/news/3628/mafia-ii-demo-tweaking-physx-performance/

Basically what you want to do is turn off the cloth physics.  I turned it off with the exception of the main character.  I guess the game was calculating all cloth physics including the stuff offscreen which causes a giant fps hit.  Now I am actually playing it over 90 fps.  Here's a livestream vid of me playing through the whole demo...
