Intel GPA 2020.3 includes functional and security updates. Users should update to the latest version.
New Features for Analyzing All Graphics APIs
 
All Tools
  • Future support is already enabled for the recently announced 11th Gen Intel® Core™ processors with Intel® Iris® Xe graphics
 
Graphics Frame Analyzer
  • Variable Rate Shading Tier2 support in Multi-frame Profiling View mode. This includes screen-space visualization of the VRS image
  • Alpha support for Microsoft DirectX* Raytracing in Multi-frame Profiling View mode
  • Initial support for Multi-GPU applications in Multi-frame Profiling View mode
  • The following improvements were added for DirectX 12 Stream mode, as observed in Multi-frame Profiling View
    • Added Microsoft Direct3D* 12 Command List debug regions and markers to the API Log and the Bar Chart
    • Debug names of resources are now shown in the Resource Viewer and in the API Log
    • Added support for Execute Indirect calls
    • Improved frame opening time by loading resource data on resource selection
  • Different types of Direct3D 12 Command Queues are now explicitly shown in Multi-frame Profiling View
  • Added Direct3D 12 Command Queue debug regions and markers to the Multi-frame Profiling View
  • Increased the precision for floating point data buffers
  • Added the ability to export buffer data to CSV with a user-defined layout
 
Graphics Trace Analyzer
  • DirectX Raytracing calls are now displayed in the thread tracks
  • Added auto-highlighting of events to make CPU and GPU synchronization more transparent. When you select a synchronization event, all events that are related to it are highlighted as well
  • CPU synchronization with SetEvent and WaitForSingle(Multiple)Object(s)
  • GPU synchronization with DirectX 12 command queue Signal/Wait calls
 
System Analyzer
  •  Increased the quality of CPU metrics on Windows by significantly increasing the granularity of CPU counters for Intel hardware

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
