Detailed Description

It is now mandatory to call agsDriverExtensionsDX11_CreateDevice when creating a device if the user wants to access any DX11 AMD extensions.

The corresponding agsDriverExtensionsDX11_DestroyDevice call must be called to release the device and free up the internal resources allocated by the create call.

Enumeration Type Documentation

◆ AGSCrossfireMode

The different modes to control Crossfire behavior.

Enumerator
AGS_CROSSFIRE_MODE_DRIVER_AFR 

Use the default driver-based AFR rendering. If this mode is specified, do NOT use the agsDriverExtensionsDX11_Create*() APIs to create resources.

AGS_CROSSFIRE_MODE_EXPLICIT_AFR 

Use the AGS Crossfire API functions to perform explicit AFR rendering without requiring a CF driver profile.

AGS_CROSSFIRE_MODE_DISABLE 

Completely disable AFR rendering.

Function Documentation

◆ agsDriverExtensionsDX11_CreateDevice()

AMD_AGS_API AGSReturnCode agsDriverExtensionsDX11_CreateDevice ( AGSContext *  context,
const AGSDX11DeviceCreationParams creationParams,
const AGSDX11ExtensionParams extensionParams,
AGSDX11ReturnedParams returnedParams 
)

Function used to create a D3D11 device with additional AMD-specific initialization parameters.

When using the HLSL shader extensions please note:

  • The shader compiler should not use the D3DCOMPILE_SKIP_OPTIMIZATION (/Od) option, otherwise it will not work.
  • The shader compiler needs D3DCOMPILE_ENABLE_STRICTNESS (/Ges) enabled.
Parameters
[in]contextPointer to a context. This is generated by agsInit
[in]creationParamsPointer to the struct to specify the existing DX11 device creation parameters.
[in]extensionParamsOptional pointer to the struct to specify DX11 additional device creation parameters.
[out]returnedParamsPointer to struct to hold all the returned parameters from the call.

◆ agsDriverExtensionsDX11_DestroyDevice()

AMD_AGS_API AGSReturnCode agsDriverExtensionsDX11_DestroyDevice ( AGSContext *  context,
ID3D11Device *  device,
unsigned int *  deviceReferences,
ID3D11DeviceContext *  immediateContext,
unsigned int *  immediateContextReferences 
)

Function to destroy the D3D11 device and its immediate context.

This call will also cleanup any AMD-specific driver extensions for D3D11.

Parameters
[in]contextPointer to a context.
[in]devicePointer to the D3D11 device.
[out]deviceReferencesOptional pointer to an unsigned int that will be set to the value returned from device->Release().
[in]immediateContextPointer to the D3D11 immediate device context.
[out]immediateContextReferencesOptional pointer to an unsigned int that will be set to the value returned from immediateContext->Release().
