Dragon Age Inquisition - DirectX function GetDeviceRemovedReason failed with dxgi_error_device_hung

If you are experiencing random crashed in Dragon Age Inquisition, please try the following. They have worked for me :

1. Disable 'Origin in game'
2. Close background programs.
3. Graphic settings :
• Reduce Texture Quality - this frees VRAM
• Tessellation  : Disabled
• Ambient Occlusion : Disabled
• MSAA : Disabled

Avoid

• Switching applications to the desktop
• Opening new applications which may make specific hardware instructions that could cause conflicts. When using Firefox or OpenOffice, I had some strange window behaviour such as a title bar with a blank window, artifacts in Inquisition and of course this crash.
