What's New

Version 4.1 of the Intel® Graphics Performance Analyzers contains the following new features:

Intel® GPA Media Performance Analyzer (New!)

  • New tool for performance analysis of Intel® HD Graphics 3000/2000 accelerated media applications
  • Ability to create media performance trace capture files for visualization and detailed analysis in the Intel® GPA Platform Analyzer
  • Capture trace files provide a system-wide picture of how your code works with Intel® Media SDK and Microsoft* DXVA2 and how media-related workloads execute on the GPU.
OpenCL Support (New!)

  • Capitalize on OpenCL support for CPU analysis tasks
General

  • Ability to analyze CPU and GPU workloads enabled by Microsoft* Internet Explorer* 9, Mozilla* Firefox* 4, and Google* Chrome*

Intel® GPA Monitor

  • Ability to track media metrics (GPU utilization with break-down to GPU engines and types of media operations) in real-time while running your application

Intel® GPA System Analyzer HUD

  • Ability to change which D3D device for the instrumented process is being used to collect metrics, while your graphics application works with multiple D3D devices
  • Ability to create Intel® Graphic Checker data capture files for further analysis with the Intel® Graphics Checker software assessment tool; the Intel Graphic Checker generates a Tool Report File that you can upload to the Intel® Software Partner Program website for access to a customized Software Assessment Report, plus several development and marketing resources designed to increase the visibility of your gaming title

Intel® GPA Frame Analyzer

  • Added Recently-Used File list to the menu
  • Display Depth Buffers (on the bubble)
  • Pixel History query enabled in tab
  • Menu option to disable the variance display in Details tab
  • Copy to clipboard support added to tree lists (CTRL+C only)
  • Export render target bitmap (right-click on frame buffers or textures)
  • Enhanced API log details (accessible via the menu)
  • Implemented the Show All Render Targets option in the Render Target Viewer panel, in order to display all the render targets in the frame no matter which ergs are selected

Intel® GPA Platform Analyzer

  • Hardware tracks and tasks support: one track for each logical CPU core is added to the Task Timeline panel, displaying state information on the tasks running on each logical core
  • Task states displayed in the Task Timeline panel; this enables you to see when instrumented tasks are actually running on a CPU core or are suspended
  • A new track containing task groups added to the Task Timeline panel, enabling you to see time spans occupied by each task group
  • New toolbar buttons for important operations
  • Trace Information dialog box providing information on the trace file including task and task group counts, and system information from the environment where the trace file was collected including graphics driver version, operating system, and a preview image taken when the trace data was collected (when applicable)
  • Track hiding and reordering: drag the tracks up and down to reorder them, remove unneeded tracks from the Task Timeline
  • Movable panels from multiple loaded files: you can tear off panels from different loaded files and arrange them side by side for easy comparison
  • Tabbed multi-document manager enabling you to quickly switch among multiple loaded files
  • Ability to open and interact with large trace files (up to 1GB in size)


Where To Next...

To start using the new workflow and features, "take the tour" of Intel GPA 4.1 by referring to the new Quick Start Guide that's installed with the product (access it through the Windows Start Menu for the Intel GPA product). An online version of the Quick Start Guide is located here; there's also an Intel GPA Getting Started Guide located here.
