Use the DirectX runtime and Visual Studio graphics diagnostic features

  • 아티클

[This article is for Windows 8.x and Windows Phone 8.x developers writing Windows Runtime apps. If you’re developing for Windows 10, see the latest documentation]

With Windows 10, the graphics diagnostic tools are now available from within Windows as an optional feature. To use the graphics diagnostic features provided in the runtime and Visual Studio to develop DirectX apps or games, install the optional Graphics Tools feature:

  1. Go to Settings, select System, select Optional features, and then click Add a feature.
  2. In the Add a Feature list, click Graphics Tools.

Graphics diagnostics features include the ability to create Direct3D debug devices (via Direct3D SDK Layers) in the DirectX runtime, plus Graphics Debugging, Frame Analysis, and GPU Usage.

  • Graphics Debugging in lets you trace the Direct3D calls being made by your app. Then you can replay those calls, inspect parameters, debug and experiment with shaders, and visualize graphics assets to diagnose rendering issues. Logs can be taken on Windows PCs, simulators, Windows Phone emulators, or devices, and be played back on different hardware.
  • Graphics Frame Analysis in Visual Studio runs on a graphics debugging log and gathers baseline timing for the Direct3D draw calls. It then performs a set of experiments by modifying various graphics settings and produces a table of timing results. You can use this data to understand graphics performance issues in your app, and you can review results of the various experiments to identify opportunities for performance improvements.
  • GPU Usage in Visual Studio allows you to monitor GPU use in real time. It collects and analyzes the timing data of the workloads being handled by the CPU and GPU, so you can determine where bottlenecks are.
