In either case Mass Effect 2 will not run and/or stop runningĤ) If you play games that require newer versoins of PhysX then you will need to uninstall Physx and reinstall PhysX_SystemSoftware every time that you want to play Mass Effect 2, and then reinstall newer PhysX whenever you switch back to your newer games so, I recommend that you keep a copy of both PhysX_SystemSoftware and whatever newer version you need somewhere on your Hard Drive in case you need to juggle them for these reasons.ĥ) You do not need to reinstall Mass Effect 2 itself, only the PhysX_SystemSoftware in order to get it running again To Fully Clarify both the Problem and the Solutionġ) PhysX drivers WILL NOT negitively effect a non-NVidia card since the software itself does not focus on the Graphics cardĢ) If you do not have an nVidia Card, and you are getting the Physx update error when trying to Run Mass Effect 2 you must uninstall any version of PhysX you have (even if other games require it) and install PhysX_SystemSoftware which is found in the software folder of Disc 2 of Mass Effect 2 (or possibly online somewhere)ģ) If you try to update to or already have newer versions of PhysX, the version that is required by Mass Effect 2 will either be overwritten, or otherwise refuse to install because it detects a newer version.
