Hi, I am new to this forum.
One of the things i like about the Pc version is Physx...
I know, that the Physx data is in the bin32 folder of arkham city and well everytime there was a new
physx system software i checked the files and eventually copied newer versions of physxcore oder cudaart in the bin32 folder...was this a mistake? maybe i should have left the folder as it was....i thought when i copy some new files of the physx software in the bin folder it makes physx run faster....does the game detect the newest physxcore for example automatically?

if yes can someone upload the original bin32 folder after the second patch...my pc cant repair previous data older than june....
i have now deleted physxcore and cudaart and have left the physxcooking and physxloader, as they areimportant to run the game and must not be changed....

sorry for the long message but i hope you can help....eventually i have to reinstall the game right???
