Game not recognising graphics card

Then you're most of the way there. The process to get your card recognized is the same as before; the reason your card is no longer found and matched is because you uninstalled and reinstalled the game. If you'd like help adding the card again, just let me know its device ID, but it sounded like you had the process figured out before you posted here.

Out of curiosity, was it enough to launch the game and refresh the deviceconfig, or did you need to take any other steps to get your laptop to start using the Nvidia card again?
