Everything seems to be fine with Amnesia, the game runs fine and the Quadro card is being used properly.
1) Let's try deleting your configuration files. Go to Documents\Penumbra Overture\Episode1\ and delete all .cfg files and try the game again (basically delete everything except the saves).
2) The latest Nvidia Quadro drivers are
314.07. Make sure you have them installed and not the default OEM ones that come with the laptop. Select clean installation during setup too. If the drivers are indeed at version 314.07, then make sure that the nvidia control panel is not changed in any way. Leave it at defaults when it comes to Penumbra and Amnesia and change any settings in-game.
3) If the above don't solve the problem, there might be a problem with old files that were created during the time that you didn't run the game with administrator privileges. Go to C:\Users\-YOUR-USER-NAME-\AppData\Local\VirtualStore and delete everything Penumbra-related. That means Documents and Program Files (steam folder). If you don't know how to do that then just rename the folder VirtualStore to VirtualStore_TEST and try running the game again as an administrator.
