P1999 Laptop graphics card

[Faxi]

Hi, got my friend started. He is playing on a laptop and we cant get the client to use his dedicated graphics card (nvidia 750m) instead of his integrated gpu (intel 620). reading through old posts we tried everything - nvidia control panel, rightclicking the exe and choosing "run with..." etc. In-game, the options window doesnt even show the nvidia 750m.

Any tips? thank you
