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.
The graphical user interface was upgraded to Qt* 6 framework and includes the latest security updates, which improve the system stability.
Added the new Frame capture mode for Microsoft DirectX* 12 based on the latest capture/playback framework, which supports DirectX 12 Ultimate features, including mesh shaders and DirectX Raytracing (DXR).
Added compression option for Stream and Frame (for DirectX 12) capture modes. This option can reduce the required storage space for captured streams and frames by up to 30%.
Graphics Frame Analyzer
Improved error messages, which allows for easier troubleshooting of stream and frame opening issues.
Note For frames captured with the new Frame mode in DirectX 12, some features are not yet supported in Graphics Frame Analyzer: Pixel History, 2x2 Textures experiments, Samplers Preview, Shader Compilation parameters, and others. These features are planned for support in future releases.
For capture-time compression, the frame rate may drop when compression is enabled, so a much smaller stream may be the result of compression and fewer frames being captured.
Intel® GPA Framework
The following features were added:
An auto-hooking feature that can attach to workloads at launch
New functionality to track acceleration structures in DXR workloads accurately that enables cross-GPU capture and playback of streams (technical preview).
A dump state layer to inspect the draw/dispatch calls by dumping state information into text files.
Capture/playback support for VK_KHR_buffer_device_address, which enables capture/playback of workloads that use acceleration structure/buffer/memory device addresses (essentially, ray tracing workloads).
At the 2022 Game Developers Conference (GDC), Intel demonstrated how to ramp up your game profiling abilities with the new DXR feature, hot spot analysis, and Intel® Xe Super Sampling (XeSS) capabilities in the Intel® Arc™ GPU.
