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.
Profiling Mode and the Metrics Pane have been updated to take into account memory peak bandwidth of a target platform, which enables proper identification of memory bottlenecks across a wide range of Intel GPUs with Xe Architecture.
Render Target Dependency Viewer graph was updated to improve the UI and user flow.
Added functionality to the Intel GPA framework:
Reduced playback overhead by using Compute Shaders to populate shader parameters for dispatch rays that are in the same CommandList in DXR workloads.
Improved playback performance by using Resource Barriers batching for state restoration.
The subcaptured stream can now include frame 0 as well as the last frame of the original stream using the improved subcapture boundary processing.
Implemented fixes for problems in several AAA gaming workloads
At the 2022 Game Developers Conference (GDC), Intel demonstrated how to ramp up your game profiling abilities with the new DirectX* Raytracing (DXR) feature, hot spot analysis, and Intel® Xe Super Sampling (XeSS) capabilities in the Intel® Arc™ GPU.
