  • Support for Vulkan* SDK version 1.3.268.0.

Release Notes

What's New in This Release?

All Tools

  • Added support for applications using Agility SDK libraries. However, the required GPU driver that fixes problems with extensions has not been released publicly yet. Problems when opening Unreal Engine 5.x applications streams and frames may still arise.

Graphics Frame Analyzer

  • Added Texture 2x2 and Variable rate shading (VRS) experiments for Stream and Frame [DX12] modes.

  • Fixed Shader Profiler bug when using DXR. As a result Shader Profiler and Shader Table are enabled for DX12 application streams and frames utilizing raytracing.

  • Fixed a bug that was preventing texture saving on hard drive.

  • Improved rendering state table for Stream and Frame [DX12] modes.

  • Static samplers are now displayed on the resources pane for Stream and Frame [DX12] modes.

Intel® GPA Framework 

  • Added support for Vulkan ray tracing workloads that allow users to perform continuous capture and playback (technical preview).
  • Added an experiment for variable rate shading (VRS) in Microsoft Direct3D 12*, enabling changing of shading rates via VRS parameters.
  • Enhanced auto hooking behavior (see the gpa-injector help documentation for more information).
  • Support for Vulkan* SDK version 1.3.250.0.

Release Notes

What's New in This Release?

All Tools

  • Upgraded GUI to Qt6 framework. It includes the latest security updates which improve system stability.

Graphics Monitor

  • Added new frame capture mode (Frame [DX12]), based on the latest capture/playback framework, which supports DirectX* 12 Ultimate features, including Mesh Shaders and DXR.
  • Added compression option for Stream and Frame[DX12] capture modes. This option can reduce the required storage space for captured streams and frames by up to 30%.

Graphics Frame Analyzer

  • Improved error messages, allowing for easier troubleshooting of stream and frame opening issues.

Intel® GPA Framework 

  • Added an auto hooking feature that can attach to workloads at their launch. It has broad functionality to control the “attach” conditions, such as any wildcard match of the process name, as well as the ability to attach to a process on its Nth invocation.
  • Added new functionality to track acceleration structures in Microsoft* DirectX Raytracing (DXR) workloads accurately, thus enabling cross-GPU capture and playback of streams (suboptimal, but correct)
  • Added a dump state layer to inspect the draw and dispatch calls by dumping state information into several text files.
  • Added capture/playback support for VK_KHR_buffer_device_address. That enables capturing/playing back workloads that use acceleration structure/buffer/memory device addresses (essentially, raytracing workloads).
  • Added support for Vulkan* SDK version 1.3.243.0.

Release Notes

What's New in This Release?

Graphics Frame Analyzer

  • Added pipeline statistics and performance metrics for shaders:
    • Mesh Shaders (MS)
    • Amplification/Task Shaders (AS/TS)
  • Updated Dependency Viewer documentation. (Formerly - Render Target Dependency Viewer)

Intel® GPA Framework 

  • Added a capture layer compression option. This can reduce the captured stream size by up to 30%, reducing storage needs over time if streams are stored for tasks such as regression testing. 
  • Improved the Intel® GPA Framework subcapture recorder tool regarding stability and support of the a broader range of DXR workloads.
  • Added dump-render-targets layer that can allow users to write out render targets to a file
  • Added support for Vulkan* SDK 1.3.239.0

Release Notes

 

All Tools

  • Support for Intel® Xe-HPG (previously known as DG2)
  • Support for Intel® Iris® Xe graphics

 

Graphics Frame Analyzer

  •  Added Shader Table for DirectX* Raytracing applications. The table visualizes all shaders that can be potentially be executed as a result of a DispatchRays call. The Shader Table contains the following performance metrics for each shader:
    • Duration,
    • Hardware thread count,
    • SIMD occupancy,
    • SIMD active channel.

  • Grouping by Debug Regions option is now persistent even if a frame doesn’t have debug regions.

Graphics Monitor

  • Added Stream and Trace mode support for the Injection skip list. It is now possible to define the list of processes which will not be injected. This feature is useful when either injection into helper processes might cause conflicts with Intel® GPA or there is no need to generate continuous streams for all forked processes.

Graphics Trace Analyzer

  • Added support for Intel® Media SDK and Intel® Video Processing Library (oneVPL).
  • Reduced overhead of Event Tracing for Windows* (ETW) and Instrumentation and Tracing Technology (ITT) data collection.

  • Added the capability to the gpa_player to report its process name as the name of the original captured process to allow profiling of the process with driver level game specific optimizations.
  • Added support for Windows 11 SDK (10.0.22000.0).

2021

Release Notes

Graphics Frame Analyzer

  • Improved bottleneck analysis and Advanced Profiling mode: :
    • More detailed reasons for bottlenecks and more accurate improvement suggestions are available.  
    • Graphics and cCompute pipeline results bottlenecks are shown in the same tab. 
  • Improved metrics collection: :
    • Added metrics subscription. When metrics table view is selected in Metrics Viewer, Graphics Frame Analyzer doesn’t automatically request all the available metrics anymore. Instead, users can configure a list of metrics of interest, group and save them into metric subscription presets. These presets as well as a list of metrics depend on selected GPU adapter. 
    • Added metrics subscription. You can now group metrics of interest into subscription presets. In Metrics (Selection) and Metrics (Frame) tabs, Graphics Frame Analyzer request values only for subscribed metrics, which helps to avoid long metrics calculation.
    • Metric updates now depend on a the selected tab. No updates on new event selection in “Metrics (full-frame)” mode, only subscribed metrics are requested in “Metrics (Sselection)” mode, and the minimal required set of metrics is requested in “Bottlenecks” mode.
    • Metric updates now depend on the selected tab. In the Bottlenecks tab, the minimal required set of metrics is requested. In the Metrics (Selection) tab, subscribed metrics are requested each time you select new events. In the Metrics (Frame) tab, only subscribed metrics for the full frame are presented. 
  • Added support for DirectX 12 Ultimate features including DirectX Raytracing
    • It is now possible to capture a stream file from applications that use DirectX 12 Ultimate features, and look for content of a stream with view hardware counters data.
    • DXIL Libraries are shown as a separate resource in the Resource List.
    • Shading Rate textures for Variable Rate Shading Tier 2 applications are shown in the Resource List.
