As Photoshop is not able to detect the GPU in your computer, with Photoshop closed could you please try adding Photoshop to the 3D program list in the Nvidia Control Panel and then launch Photoshop & let us know if it works?
Hey! I did it and it worked. This way if you have 2 graphic cards you can choose which one Photoshop should use. Thanks for help ;]
Glad it's working for you! Feel free to reach out to us for any future queries!
