What's New with Intel® Graphics Performance Analyzers

Intel GPA 2021.3

  • Graphics Frame Analyzer
    • Added support for streams from multi-queue DirectX12 applications. You can now open a frame for detailed analysis from the Multi-frame View window.
    • Updated the central panel for better user experience. The full set of bound resources is now presented as a vertical list with searching and filtering capabilities.
    • Added combined state view with both pipeline state object (PSO) and non-PSO states for stream files. Now the table visualizes the state structure in a similar way to DirectX12 header.
  • Graphics Trace Analyzer
    • Added tracing for multi-CPU systems.
    • Added Media SDK support. Added media Instrumentation and Tracing Technology (ITT) events into thread tracks and visualized relations between these events and UMD queues with arrows.
    • Implemented OpenGL* screenshot capturing for the trace files. In OpenGL trace file preview, you can now see an actual screenshot captured from the application instead of a generic icon.
    • Added the ability to copy data from the Summary Table to a clipboard.
    • Improved the timeline initialization. Now trace loading time can be reduced up to 25%.

Intel GPA 2021.2

  • Graphics Frame Analyzer
    • Added the Dependency Viewer tool for D3D11 applications. You can now build a scene graph and explore dependencies between resources within a frame in detail.
    • Enabled D3D12 Pipeline statistics metrics in Multi-Frame View. You can now see pipeline metrics right in the
      Stream Content
       pane, giving you more information when selecting a frame for detailed analysis.
    • Added support for applications with D3D12 Render Passes in
      Stream
       mode.
    • Added warning for opening Stream files captured on another GPU and/or with a different driver.
    • Improved quality of D3D12 multi-frame Stream support.
  • Graphics Trace Analyzer
    • Added visualization for Render and Present queue packet relationship with CPU thread calls. You can now trace the origins of these packets by clicking on a Render or Present packet.
    • Enhanced track utilization indicators: they now show duration and percent of track activity for current zoom area.
    • Added D3D12 Pipeline statistics metrics. You can now see pipeline metrics right on the Trace Content pane and correlate these metrics to frames in a trace.
    • Added support for OpenGL tracing on Windows (Tech Preview).
  • Graphics Monitor
    • For security reasons, real-time overrides, such as Wireframe, have been removed.
    • Vulkan support on Ubuntu was discontinued due to low demand.

Intel GPA 2021.1

  • Graphics Frame Analyzer
    • DirectX 12 Multi-frame profiling for stream files with significantly improved quality of stream capture/playback. Multi-frame profiling for DirectX 12 streams is now fully supported and is enabled by default.
    • DirectX 12 Queue call markers in Multi-Frame View For DirectX 12 streams, markers that highlight points in time when each queue call was made are now shown directly on the time line. Calls from all queues are visible. You can also click each marker to select the corresponding call on the
      Stream Content
       pane.
    • In Frame Analyzer, the metrics table now shows both plus and minus signs for positive and negative values in the "Delta" column, respectively.
  • Graphics Trace Analyzer
    • CPU threads synchronizations via SetEvent/WaitForSingle(Multiple)Object(s). Synchronization relations can now be traced all the way to the CPU thread that resumes execution after receiving a signal.
    • Active and inactive thread zones visualization. On the
      Trace Content
       pane, green bars now highlight areas where a thread was active. Areas where a thread was idle are highlighted with gray bars.
    • Default 100% Y-axis scaling for percentage metrics. Percentage metrics are now auto-scaled to 100% to help estimate the disparity between different metrics quicker.
