apitrace vs Superluminal Performance Profiler

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.
