You can try to do this using the video driver settings menu. This is the example of NVIDIA, but it's possible that AMD will have similar settings. Go to the setting of the discrete graphics card drivers. Next, in the menu on the left, select "Manage 3D settings", then in the "Preferred graphics adapter" column, select "High-performance NVIDIA processor", then save the settings. After that, you can try to start the game. I had a similar situation, but with Photoshop, since I needed to do large-scale illustrations for my feasibility study on AnswerShark, and the embed Intel would not cope with this task. Also, in the settings of NVIDIA, you can specify the specific game for a particular game video card.
