To access the Multiframe View window, select a stream for analysis in the Open Frame Capture window, and then click Open, or double-click on a stream preview.


Multiframe View is available only for Vulkan and OpenGL applications.


Stream Title bar

Displays the opened stream file name.

Stream Information panel

Displays the opened trace data, notifications, opens the Intel® GPA User Guide, restores the default view, and changes the Intel® GPA color scheme.

Stream Content List pane

Filters tracks, shows event duration, zooms to the selection and zooms out.

Stream Viewer pane

Visualizes the opened trace content.

Stream Title Bar

Multiframe View Stream Title bar shows the opened stream file name. The file name consists of the application name, capture date and time in the following format: YYYY_MM_DD_HH_MM_SS.

Stream Information Panel

Back button

Returns to the Open Frame Capture window. You can use the Backspace key instead.

Stream Overview pane

Provides the following statistical information for the opened stream:

  • Duration of the full stream, in seconds.
  • Duration of the selected frames, in microseconds.
  • Theoretical frame rate for the selected frame or average frame rate for the several selected frames, in frames per second (FPS). To see the frame rate, select full frames.

Message pane

Displays messages and non-critical errors.


If more than one message is open, use the Up or Down arrows to navigate between messages.

Settings button

  • Changes the color scheme of the Graphics Frame Analyzer interface:

    • Light color scheme (default)
    • Dark color scheme


Send feedback

 Opens a form to send feedback to the Intel® GPA technical support.

Help button

Opens the Intel® GPA online documentation.

Stream Content List Pane

Type Filter Expression field

Filters frames by number or duration. Saves previous search keywords. You can use the Type Filter Expression field, to find specific frames by running Graphics Frame Analyzer plugins.

Execute Plugins button

Opens the list of the available Graphics Frame Analyzer plugins.

Collapse All Groups button

Closes all the groups in the Frame List tab, if available.

Export Frame Log button

Saves the Frame log in CSV format. You can also save the Frame log by pressing Ctrl+S.

Frame List tab

Lists all frames of one rendering context/queue in the CPU execution order. The number of Frame List tabs depends on the number of rendering contexts/queues in the opened stream.

To profile an individual frame, double-click the required frame; or click the required frame, and then click Open.


Initialization frame cannot be opened for profiling.

    For Vulkan-based application streams, the Multiframe View shows subframes:

    • Queue Submit calls. Submit calls can be selected and opened in the Profiling View.

    • Queue Present calls. Present calls can be selected.

Open button

Opens the selected frames in the Profiling View. You can select one frame or several frames. For Vulkan-based applicaitons, you can also select subframes.

Stream Viewer Pane

Timeline ruler

Correlates all the displayed frames with the timeline. The range of the timeline corresponds to the length of the stream in the current zoom level. Depending on the zoom-in level, the time intervals are displayed in seconds, milliseconds, microseconds, or nanoseconds.

Zoom to Selection button

Zooms into the time range of selected frames.

Full Zoom Out button

Restores the default zoom level.

Context/Queue bar chart

Visualizes individual frames, their contribution to the overall stream time in the CPU execution order, and keyframes. Keyframe is a saved state of an application, from which you can play back the captured stream.

When you select a frame in the Frame List tab, the corresponding bar is highlighted on the Context/Queue bar chart. If you select only part of a frame, the corresponding bar is hatched. Keyframes are shaded grey.

CPU time is measured in microseconds.

You can change the vertical scaling of the bar chart by increasing or decreasing the relative height of the bars using the or  buttons respectively. By default, all bars are displayed in their original height.

To enable or disable the vertical auto-scaling, click the / toggle button. By default, the vertical auto-scaling is enabled.

To switch to the line chart view or to the bar chart view, click the / toggle button. The bar chart view is default.

To profile an individual frame, select a frame bar on the Context/Queue bar chart, and then click Open.
