Release Notes

Across All Tools

Intel® Arc™ GPU cards are now available. This new GPU family supports the latest DirectX 12 Ultimate API features, including DXR, Mesh Shading and variable-rate shading (VRS) (Tier 1 and 2).

Graphics Frame Analyzer

• The Intel® Arc™ GPU features can be profiled in Graphics Frame Analyzer, including Intel® Arc™-specific hardware metrics.
• Render Target Dependency Viewer: The Dependency Viewer was first available in our June 2021 release. We have made several improvements to the UI, making user workflow more efficient..
• We have made updates to take into account memory peak bandwidth of target platforms for proper identification of memory bottlenecks.

Intel® GPA Framework 

• 20-40% framerate increase on GPA playback of captured streams from DXR-enabled games: Modified the way shader parameters for dispatch rays calls are processed. This applies to Direct3D12 DXR workloads. 
• Reduced playback overhead by using Compute Shaders to populate shader parameters for dispatch rays that are in the same CommandList in DXR workloads.
• Improved playback performance by using Resource Barrier batching for state restoration.
• Improved the Intel® GPA Framework subcapture recorder tool so that it can now capture the first frame and the last frame. You can compress the entire stream and/or filter out unnecessary resources and API calls. You can also create subcaptures (without the compression and/or filtering) with those frames.
• Lower the barrier of entry to working with Vulkan by using developer-friendly abstractions in Intel® Graphics Performance Analyzers Utilities for Vulkan*

Keyframing is deprecated: replaced by Deferred Capture and Sub-capture, for more control and flexibilty. More info.

Release Notes

Intel® GPA Framework 

• Enhanced gpa-metrics-collector command:

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.

• View all available Intel® GPU metrics metrics in System View on Windows* Platforms, with an ability to switch between these counter sets using the Ctrl+M hotkey.
• Search for and pin interesting metrics to the top of the metrics table.
• Copy resource names in the Resource Viewer using CTRL+C.

Release Notes

OVERVIEW

• API Log pane now contains a new Frame Statistic tab, and separate tabs for Resource History and Pixel History. The Resource History tab enables you to select a target resource, and in the Pixel History tab you can select pixel coordinates.
• Input/Output Geometry viewer now provides additional information about the topology, primitive count, and bounding box.
• New User Interface for DirectX* 11 frames.

Release Notes

OVERVIEW

• Profile Windows Mixed Reality applications on the Windows Fall Creators update.
• New User Interface for DirectX 11 frames with additional features.
• Hotspot Analysis mode available for DirectX 12 and DirectX 11 (new UI) frames. Users can now easily find the most problematic events in a frame by bottleneck.

Release Notes

OVERVIEW

• Trace Analyzer now is the only timeline tool in Graphics Performance Analyzers suite. Platform Analyzer tool has been removed. API Log and Metrics can be exported now.
• The accuracy of time-based GPU metrics in System Analyzer has been significantly improved.
• Support for Windows Mixed Reality titles in simulation mode added.

Release Notes

OVERVIEW

• Runtime overhead was improved for Windows* applications.
• Graphics Monitor has been implemented for macOS* and Ubuntu* platforms. It has the same functionality as the Windows* version excluding support for Tracing and Triggers.
• System Analyzer HUD for OpenGL* applications implemented.

Release Notes

OVERVIEW

• Improved workflow for opening trace files. Added a new trace file open dialog which includes trace file previews and system information.
• The Metrics Viewer now shows primary or potential bottlenecks with detailed descriptions for a current selection.
• The GPGPU pipeline was added into the Metrics Viewer to support bottleneck analysis for Dispatch calls.

Release Notes

OVERVIEW

• Bar Chart now supports grouping draw calls by regions (debug regions, shader usage, etc.) for Microsoft DirectX* 12 and OpenGL* APIs.
• Trace Analyzer is a new timeline analysis tool supplemental to Platform Analyzer. At this moment, Trace Analyzer provides the same functionality as Platform Analyzer and adds support of platform analysis of desktop OpenGL* applications on Ubuntu* systems.
• Added support for VR games (tested on HTC Vive* and Oculus Rift*).

Release Notes

OVERVIEW

• Enabled API log export into a text file.
• Added Pixel Overdraw view for render targets.
• Updated Metrics Viewer in accordance with the latest performance optimization guide.

Release Notes

OVERVIEW

• Enhanced DirectX 12 profiling capabilities by adding new product features and improving product performance.
• Enabled capturing and profiling DirectX 12 workloads on a remote system.
• Added Active API drop-down menu for switching between API types in the Preferences dialog box, to replace the Force DirectX 12 Injection checkbox.

Release Notes

OVERVIEW

• Intel GPA now stores all captured frames, traces and other important files in a single GPA folder under Documents on Windows, or Home on Ubuntu/OS X, irrespective of the product version. Now you do not need to repeatedly copy files and change settings each time Intel GPA is updated.
• Graphics Frame Analyzer tools got renamed. If you would like to profile Microsoft DirectX* 9, 10, 11 frames, you should use “Graphics Frame Analyzer (DirectX 9,10,11)” tool. In case you need to profile OpenGL*, OpenGL ES or DirectX 12 applications, use “Graphics Frame Analyzer”.
• Detailed GPU hardware metrics for Intel® graphics. For third-party GPUs, GPU Duration and graphics pipeline statistics metrics are available.
