AMD GPU Services (AGS) Library

SDKs & Libraries


AMD GPU Services (AGS) Library

The AMD GPU Services (AGS) library provides software developers with the ability to query AMD GPU software and hardware state information that is not normally available through standard operating systems or graphic APIs. AGS includes support for querying graphics driver version info, GPU performance, Crossfire™ (AMD’s multi-GPU rendering technology) configuration info, and Eyefinity (AMD’s multi-display rendering technology) configuration info. AGS also exposes the explicit Crossfire API extension, GCN shader extensions, and additional extensions supported in the AMD drivers for DirectX 11 and DirectX 12. Version 5.0 adds support for HDR displays, as well as a Microsoft WACK compliant version of the library.


Version 5.0 is a major overhaul of the library designed to provide a much clearer view of the GPUs in the system and the displays attached to them. It also exposes the ability to query each display for HDR capabilities and put those HDR-capable displays into various HDR modes. Highlights include the following:

  • Full GPU enumeration with adapter string, device id, revision id and vendor id.
  • Per-GPU display enumeration including information on display name, resolution, and HDR capabilities.
  • Optional user-supplied memory allocator.
  • Function to set displays into HDR mode.
  • A Microsoft WACK compliant version of the library.
  • DirectX 11 shader compiler controls.
  • DirectX 11 multiview extension.
  • DirectX 11 Crossfire API updates.
    • Now supports using the API without needing a driver profile.
    • You can also now specify the transfer engine.

Driver extensions

AGS exposes GCN shader extensions for both DirectX 11 and DirectX 12. It also provides access to additional extensions available in the AMD driver for DirectX 11:

  • Quad List primitive type
  • UAV overlap
  • Depth bounds test
  • Multi-draw indirect
  • Multiview


In addition to the library itself, the AGS SDK includes several samples to demonstrate use of the library:

  • AGS sample
    • A “hello world” for AGS to demonstrate basic usage
  • Crossfire™ sample
    • Demonstrates the explicit Crossfire™ resource synchronization API
  • Eyefinity sample
    • Demonstrates using AGS to query multi-monitor information

System requirements

  • AMD Radeon™ GCN-based GPU (HD 7000 series or newer)
  • 64-bit Windows® 7 (SP1 with the Platform Update), Windows 8.1, or Windows 10
  • Visual Studio 2013 or Visual Studio 2015
