Return to the Open Frame Capture window.

Get statistics for the opened stream:

Сut the selected frames from the stream and save them into a new stream. This can be useful when a long stream only contains a few frames of interest. Trimming such a stream can save both disk space and processing time.

Enable the

Multi-Frame Profiling View

(DirectX Tech Preview) toggle in

Settings

to enable the

Trim Stream

button.

Filter frames by number or duration. Save previous search keywords. You can use the

Type Filter Expression

field to find specific frames by running Graphics Frame Analyzer plugins.

Open the list of the available Graphics Frame Analyzer plugins, which help you to find specific frames. For example,

Frame Search Assistant

plugin searches for a frame of the specified duration.

Close all the groups of events and commands for each frame in the

Frame List

tab, if available.

Save the frame log in CSV format. You can also save the Frame log by pressing

Ctrl+S

.

Get the list of 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

.

For Vulkan-based application streams, the

Multiframe View

shows subframes:

For applications based on Microsoft DirectX* 12 that use several command queues, the frame list shows each queue in a different tab:

For DirectX 12 applications with command queues that are instrumented with events, each frame can be expanded to view individual events and their details:

Open the selected frame in the Profiling View window. For Vulkan-based applications, you can select several frames and subframes.

Correlate all the displayed frames with the time line. The range of the time line 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 into the time range of selected frames.

Restore the default zoom level.

Visualize 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.

Bars for selected frames are highlighted on the

Context/Queue

bar chart. If you only select a part of a frame, the corresponding bar is hatched. Keyframes are shaded grey.

By default, streams are visualized on the

GPU Time Elapsed

track. You can visualize other GPU metrics by selecting a sampling interval other than

Frame

in the

Metrics

tab of the Graphics Monitor

Options

before you start an application on

Stream

mode. When you set a sampling interval other than

Frame

, metrics are collected system-wide with the chosen frequency.

For DirectX 12, calls from the queues are also shown on the bar chart, represented as markers with downward-pointing triangles. Each marker represents a point in time when a certain call was made. All markers extend downwards, which enables you to correlate calls to the overall frame and GPU metrics, such as

GPU Busy (%)

.

You can also click on each call from the

Frame List

tab to highlight the corresponding frame and marker on the bar chart.

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.
