Graphics Log Document

A graphics log document is a record of the Direct3D events that were captured from your game or app during a graphics debugging session. You can examine the log in Visual Studio to identify rendering errors so that you can use the Graphics Diagnostics tools to inspect them in more detail.

This is what a graphics log document looks like in Visual Studio:

A graphics log containing two captured frames.

By using Visual Studio to examine a graphics log document, you can visualize the effects of Direct3D events on the render target that occurred during capture. You can pinpoint regions of the render target that contain unexpected output. When you select a pixel in the affected region, you can use Graphics Diagnostics to inspect it, its shaders, the Direct3D events that affected it, the application call stack that led to those events, and the DirectX objects that support those events. You can use this information to diagnose rendering problems in your game or app.

The top part of the window (Graphics Experiment.vsglog) displays the current render target output of the selected frame, and the bottom part displays a Frame List that contains thumbnail images of the captured frames.

To inspect a frame

  • In the Frame List, select the frame that you want to inspect. The render target output in the top part of the graphics log document is updated to display the selected frame.

To inspect a pixel

  • In the top part of the graphics log document, select the pixel that you want from the render target output. When a pixel is selected, you can use the Graphics Pixel History window to view detailed information about the selected pixel. For more information, see Graphics Pixel History.

When a graphics log file is the active document, the Properties window displays information about the environment that hosted the Graphics Diagnostics capture session. Several categories of information are displayed.

Direct3D Information

Lists information about the hardware and driver features of the display adapter that was used during the capture session.
