For DirectX 11 applications, AGS provides critical enhancements:
AMD’s AMD GPU Services (AGS) library provides software developers with direct access to AMD Radeon graphics hardware features that are not standard in graphics APIs. For games and applications utilizing DirectX 11 (DX11), the AGS Driver Extensions allow developers to unlock advanced capabilities like crossfire explicit control, specialized shader instructions, and deep hardware queries. ags driver extensions dx11 init download install
The Ultimate Guide to AGS Driver Extensions for DX11: Download, Initialization, and Installation
The AMD GPU Services (AGS) library is a software development kit (SDK) designed for game developers and graphics programmers.
Go to Project Properties > C/C++ > General > Additional Include Directories and add the path to the folder containing amd_ags.h . /inc : Contains amd_ags
Here is the structured programming workflow to initialize AGS on DX11:
#include #include "amd_ags.h" // 1. Declare AGS global pointers AGSContext* g_agsContext = nullptr; AGSGPUInfo g_gpuInfo = {}; void InitializeAGSDX11() { // 2. Initialize the AGS Library AGSConfiguration config = {}; AGSReturnCode result = agsInitialize(AGS_MAKE_VERSION(6, 0, 1), &config, &g_agsContext, &g_gpuInfo); if (result == AGS_SUCCESS) // AGS successfully attached to the AMD graphics driver // g_gpuInfo now holds architecture details, VRAM capacity, and device IDs } // 3. Create DX11 Device with AGS Extensions IDXGIAdapter* pAdapter = nullptr; // Select your AMD adapter here D3D_FEATURE_LEVEL featureLevel; ID3D11Device* pDevice = nullptr; ID3D11DeviceContext* pContext = nullptr; // Set up your standard DX11 creation parameters... HRESULT hr = D3D11CreateDevice( pAdapter, D3D_DRIVER_TYPE_UNKNOWN, // Must be UNKNOWN if pAdapter is not null NULL, 0, NULL, 0, D3D11_SDK_VERSION, &pDevice, &featureLevel, &pContext ); if (SUCCEEDED(hr) && g_agsContext) // 4. Notify AGS of the newly created DX11 device // This activates the proprietary AMD driver extensions on this specific device context unsigned int extensionsSupported = 0; agsDriverExtensionsDX11_Init(g_agsContext, pDevice, &extensionsSupported); Use code with caution.

To avoid access violations and memory leaks during application shutdown, call agsDriverExtensionsDX11_Deinit before releasing your main ID3D11Device object.
Once initialized, you can use agsDriverExtensionsDX11_Init to hook into specialized functionalities.
Implementing AGS Driver Extensions for DirectX 11 requires downloading the AGS SDK from AMD GPUOpen, linking the library into the application build, and deploying the requisite DLL. Successful initialization relies heavily on the end-user having a modern AMD graphics driver installed. This integration is strictly for developers seeking to optimize for AMD hardware and is not a standard user-installable software patch.
