Intel® Graphics Performance Analyzers Framework
A command line and scripting interface allows users to access frameworks that expose capture and playback functionalities in Intel® Graphics Performance Analyzers (Intel® GPA). Capture multiframe streams, analyze stream data, generate reports, and automate profiling to spot or flag performance regressions.
Hot Spot Analysis
Quickly identify the most expensive events by their hardware bottlenecks.
Multiframe Analysis
Capture a continuous stream of frames to identify intermittent rendering issues and spikes in frame times.
System-Level Profiling
Correlate captured data from ETW events, ITT user markers, graphics API calls, and high-frequency metrics all in one timeline.
Shader Profiling
Optimize shaders more efficiently by identifying the most expensive calls.
What's New: Release 2025.1
- Added full support for Intel® Arc™ B-Series graphics.
- Re-enabled the Shader Profiler for Microsoft DirectX* 12 applications.
- Added initial support for displaying DirectX 12 acceleration structures, showing top-level acceleration structure (TLAS) and BLAS hierarchical trees.
- Improved analysis for bottlenecks. Metric values are now collected only for the API calls involved with the bottleneck.
- Enhanced UI and UX:
- Resource IDs are displayed in hexadecimal format.
- A GPU auto-selection feature was added.
- The playback GPU name appears in the window header.
- Added functionality to the Intel GPA Framework:
- Experimental support for DirectStorage.
- Support for Direct3D 11 video interfaces on the D3D12 runtime during deferred capture.
- A gpa-player parameter for manual error handling control.
- Support for Vulkan* SDK v1.4.304.0.
