 ## How does it work?
 
 The primary entrypoint to D3D11On12 is a custom version of the normal D3D11 driver [OpenAdapter10_2](https://docs.microsoft.com/en-us/windows-hardware/drivers/display/initializing-communication-with-the-direct3d-version-11-ddi) entrypoint, named `OpenAdapter_D3D11On12`, where D3D11 provides additional information to the mapping layer. In response to this, like a normal driver, D3D11On12 returns an adapter object, which exposes DDIs to create a device. The device is created like normal, but in addition to the normal DDI tables, it also exposes an `ID3D11On12DDIDevice` interface.
