Known Issues and Limitations

For Intel® GPA Framework

  • User input for keyframes and deferred stream capture may not be registered in certain applications. Please use time-interval keyframes and capture layer parameters for deferred stream capture.
  • When using the AMD* RX Vega card to capture a stream on a Hades Canyon machine the argument "--page-tracker-mode 2" must be added to any ./gpa-injector command in order to properly capture the stream. Note that this does not apply to the iGFX card.
  • Intel® GPA Framework has been released for Vulkan, but there is also functionality for other graphics APIs that has been exposed and can be utilized.
  • At present, the Intel® GPA Framework contains only Release builds (no debug builds of libraries).
  • The capture layer supports only 64-bit applications. However, the injection mechanism will work with 32-bit processes for the purpose of allowing the capture of applications that require 32-bit launchers.
  • A modification of shaders in HSLS representation can cause the gpa-player to crash if the original shader representation was different from HLSL (Vulkan).
  • Support for MetricsExtractor metrics collection from compute queues is preliminary using the D3D12 and Vulkan Pipeline Statistics and Timestamp Query Managers. There is no support provided for copy/transfer queues.

For DirectX Applications

  • Parallel Execution View is not supported on Skull Canyon platforms. 
  • Applications that are dynamically linked to Microsoft* Visual C++ Runtime Library, Version 14.0 or higher cannot be launched on Windows 7 platforms with Auto-Detect Launched Applications mode enabled. You can start the application directly from Graphics Monitor or the command line. 
  • To collect stable metrics on third party graphics solutions, enable Developer Mode in Microsoft Windows OS settings. 
  • A few DirectX 11 applications that create a temporary Direct3D* 11 device may crash if started from Graphics Monitor. To resolve this issue, please enable the System-wide Time-based GPU Metrics option in the Metrics tab of the Graphics Monitor options. 
  • In rare cases, a DirectX 12 frame opened on 11th generation Intel® Core processors may display an incorrect value for the DirectX 12 PS Invocation metric for events that are preceded by a SetPipelineState call. 
  • Graphics Frame Analyzer does not display the DirectX 12 Pipeline Statistics metrics for frames that contain ClearState or SetProtectedResourceSession calls. 
  • In rare cases, a DirectX 12 frame opened on 11th generation Intel® Core processors may display an incorrect value for the EU Thread Occupancy metric for Dispatch events. 
  • Collection of CPU hardware metrics is not available in Intel® VTune™ Profiler when Graphics Monitor is running.

For Vulkan Applications

  • To profile Vulkan titles, make sure to download the latest Vulkan runtimes and SDK.
  • To enable Ubuntu support, please read the enabling instructions to view metrics on Ubuntu platforms.
  • Vulkan applications that run on multi-GPU machines and explicitly enumerate graphics adapters to render on the non-default adapter may produce stream files that cannot be analyzed in the Profiling View of Graphics Frame Analyzer. Please only keep one GPU active in Windows Device Manager to resolve the issue.
  • Graphics Frame Analyzer may show incorrect content of swap chain images if the application does not use intermediate render targets and renders directly into the swap chain image.

For Metal Applications

  • To run and profile applications from Steam*, manually download and update to the latest 64-bit version of Steam.
  • 32-bit applications are not supported for profiling.
  • Playback of the Metal stream files captured with earlier Intel® GPA versions is not supported. Old Metal stream files can be converted to the new stream format using the following steps:
    1. Open Terminal and change the directory to
      cd /Applications/Intel/
    2. Capture a new stream of the old player running the .gpa_stream file that you want to convert by the following command:
      ./gen2/gpa-injector ./gpa-playback --layer capture -- <path-to-old-.gpa_stream-file
    3. The newly converted stream is automatically added to ~/Documents/GPA/ and is displayed in the Graphics Frame Analyzer open file dialog.
  • macOS users who are running OS X* El Capitan or newer must disable System Integrity Protection (SIP) in order to profile Steam applications. If SIP is enabled on your machine, a message will appear at the top of Graphics Monitor directing you to disable it. If you would prefer not to disable SIP but need to profile a Steam application, use the following process:
    1. Launch and sign into Steam
    2. Locate the executable of the desired application and copy the location, it typically looks something like this:
      /Users/YOUR_USER_NAME/Library/Application\ Support/Steam/steamapps/common/YOUR_APPLICATION_BINARY 
    3. Launch Graphics Monitor
    4. Paste the location of desired application in the first input box and hit start
    5. Intel® GPA will now be injected into the executable, allowing for live profiling and Trace/Frame/Stream Capture
