Diablo 3 runs on integrated graphics, but gets stuck on dedicated graphics

I would like to play Diablo III, and I have installed it on my laptop with Windows 10. I have a computer with 2 graphic cards. The first one is a low quality Intel embedded with the motherboard, the other one is an AMD Radeon HD 5000.

I was asked to install Battle.net, so I did, as well as DirectX. I have also installed the newest AMD drivers.

Using the integrated Intel GPU, the game runs, but at a really low quality.
Using the AMD GPU, the game gets stuck at the opening. The screen turns black, and there is just a cursor and music.

Why does it run with the integrated Intel GPU, and what do I need to do to run it with the dedicated AMD GPU?

Can you play Diablo 3 on integrated graphics?

Note: NVIDIA GeForce 8800 GT, ATI Radeon HD 2900 XT, and Intel HD Graphics 4000 are the minimum required cards to run Diablo III. Using a slower video card may lead to performance issues in-game. If your video card is not listed here, it does not meet the minimum system requirements and is not supported.

How do I switch between integrated graphics and dedicated graphics?

Right-click on the desktop and select Nvidia Control Panel.

Switch to Manage 3D settings in the left-hand pane.

Switch to the Program Settings tab.

Under Select a program to customize, choose the relevant app.

Under Select the preferred graphics processor for this program, choose the GPU you prefer.

Can I run integrated and dedicated graphics simultaneously?

There are several reasons why companies don't allow you to use the two together. The short answer is that the dedicated graphics card, which is a much faster unit, will end up hitting a bottleneck every time it delegates performance to the slower card, which will be your integrated controller.

How do I force a game to play dedicated graphics?

Right-click the app you want to force to use the dedicated GPU. The right-click context menu will have a 'Run with graphics processor' option. Select 'High-performance NVIDIA processor' from the sub-options and the app will run using your dedicated GPU.
