apitrace vs GFXReconstruct

apitrace records OpenGL, Direct3D and DirectDraw API calls in trace files for replay and examination. Recorded calls can be replayed on another machine; OpenGL traces can also be replayed across operating systems. Its tools let users inspect graphics state and call data, view framebuffers and textures, edit trace files and profile performance. Coverage varies across APIs and operations: the feature matrix spans OpenGL 1.0–4.5, OpenGL ES 1.0–3.0, Direct3D 7–11.x and DirectDraw. Command-line profiling can capture frame, GPU, CPU and pixels-drawn data, with shader-profile formatting available through a script. The operating-system matrix lists Linux, OS X and Windows for tracing, replay, command-line and GUI use. Windows and Linux binaries are available for x86_64 and Arm64, with Windows x86 binaries also provided. The open-source project is licensed under MIT. One stated limitation is that programmatic Direct3D capture interfaces are unsupported. The maintainer says patches, issues and requests are handled as time permits, and the project links to a manual, bug-reporting guide, source-hacking guide, wiki and mailing list.

GFXReconstruct is a free toolkit for capturing and replaying graphics API activity, including Vulkan and Direct3D 12. Capture records API calls, parameters, and state in a file; replay can run without the application that created it. The repository includes capture layers and libraries, replay, capture information, compression, SPIR-V extraction, conversion, and optimization tools. Listed uses include reproducing defects, examining API usage, profiling performance, regression testing, and platform bring-up. Vulkan capture and replay are listed for Windows, Linux, macOS, and Android, while Direct3D 12 capture and replay are listed for Windows only. The maker names Samsung Sokatoa, Arm Frame Advisor, Google Android Performance Analyzer, and Qualcomm Snapdragon Profiler as tools powered by GFXReconstruct. Vulkan users can also use it alongside Vulkan validation layers and the Vulkan Configurator. OpenXR support is experimental, covers limited features and a small number of apps, and is not enabled in the SDK-built version. Cross-operating-system replay may work in some cases, but is not generally supported unless specified. The project uses the MIT License.
