Batman: Arkham Asylum PhysX Patch

This DLL patch is required to ensure that PhysX for rigid bodies works correctly in the game
We have a new patch for the Batman: Arkham Asylum owners with GeForce GTX 480 and 470 GPUs (thanks: The Patches Scrolls). In order to experience Batman: Arkham Asylum to its fullest extent when running PhysX on GeForce GTX 480 and 470 GPUs, users will need to replace the existing RRB.DLL file with a new one. In most configurations, the RRB.DLL can be found in the "Square EnixBatman Arkham Asylum GOTYBinaries" directory. If it is not located in this directory, please do a search for the filename on your system. The PC demo can be found here.
