Frame Analysis: Analyze Frames for Performance Bottlenecks

Use Intel® GPA Graphics Frame Analyzer to identify bottlenecks in the graphics pipeline. Capture a
(a sequence of frames), focus on a particular
and explore API calls and graphics resources of this frame.
To start frame analysis:
  1. Run Graphics Monitor by double-clicking the Graphics Monitor icon in the taskbar notification area or on the desktop.
  2. Specify the application for analysis by clicking the
    button on the lower right and browsing to your application ().
    On Windows, you can use the sample application
  3. Select the
    startup mode from the drop-down menu on the lower right ().
  4. Run the application by clicking the
    button ().
    The application launches in a separate window. By default, stream capture starts immediately when the application is started.
  5. Complete stream capture by pressing
  6. Open the trace using the
    Open File
    ribbon of the Graphics Monitor window ().
    Multiframe View
    of Frame Analyzer opens.
  7. For detailed analysis, open a frame that appears to perform poorly. For example, identify the longest frame by analyzing the
    GPU Time Elapsed
    metric, which shows the amount of time spent on frame rendering:
    1. On the
      GPU Time Elapsed
      track, click the longest frame ().
    2. Click the
      button on the lower left ().
    Profiling View
    window of Frame Analyzer opens.
  8. Start analysis with the
    Advanced Profiling Mode,
    which allows you to identify potential bottlenecks. Click the
    Advanced Profiling Mode
    button on the top left.
    The API calls are grouped by bottlenecks on the
    () and
    API Log
    () panes. The first group of draw calls is the most impactful and time-consuming.
  9. Start resolving issues with the most impactful bottleneck. Click the first group of draw calls either in the
    API Log
    The resources associated with this group of calls appear in the
    pane. The
    tab presents the graphics pipeline color-coded by bottleneck distribution. Red portions of the pipeline indicate main bottlenecks, and orange indicate secondary bottlenecks.
  10. In the
    tab, click the red bottleneck, for example,
    Local/Host Memory: Graphics-to-Memory Interface.
    The bottleneck cause, hints, and related metrics appear.
  11. Once step 10 is done, close Graphics Frame Analyzer window.
As a result, you can identify potential bottlenecks of your application and get hints on how to resolve issues.
