Re: PhysX System

I have Mass Effect 1 and 2 on Steam and Mass Effect 3 on(of course) Origin.  When I installed them all on my Windows 8 ME1 show a "Catastrophic Failure" and would not load.  ME2 loaded fine, that is until I completed installing ME3. At that time it stated that the Phsyx was not able to be activated.  Here were my solutions, hopefully they wil help you.

For Mass Effect 1 I went to the root folder within steam for it and tried running different .exe files in compatability mode until I found one that worked.  Now it runs great, and looks better than ever.

For Mass Effect 2, I attempted to update the NVidia Phsyx System Software but that did not work.  Instead, go to the Root folder which in my case was Program(86)/Steam/Steam Apps/Common/Mass Effect 2/Redistribut  In there you will find the installer for the version of Physx which came with it.  Go to the Uninstall a Program from your Contro Panel and Uninstall the current Nvidia Physx and then install the previously mentioned one.  ME2 will run great.

For Mass Effect 3 you will have to go to the Program(86)/Origin Games/Mass Effect 3/Redistr file to update the Physx drivers for it.  When you want to play ME2 again you will just have to rinse and repeat.  Hope this helps
