Low FPS issue.

You selected everything at Driver Sweeper? That's why that happened. I told you to select NVIDIA, PHYSIX, ATI, AMD which are for graphics. All the other things are for internet, sound maybe and stuff like that. Windows 7 should detect the drivers, if not you will now have to reinstall them. Can Amnesia be played now though? If you did everything there correctly only the graphics should be reinstalled. But it could be the card like Jens said, it is old and can barely run the game.
