GFXReconstruct
GFXReconstruct is a free, open-source toolkit for capturing and replaying graphics API activity, including Vulkan and Direct3D 12.
What GFXReconstruct is
GFXReconstruct is a free, open-source 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 produced it. The repository includes capture layers and libraries, replay, capture information, compression, SPIR-V extraction, conversion, and optimization tools. Listed uses include reproducing defects, analyzing API usage, performance profiling, 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. It can be used alongside Vulkan validation layers and the Vulkan Configurator. OpenXR support is experimental, limited to some features and a small number of apps, and not enabled in the SDK-built version. Replay across operating systems may work in some circumstances, but is not generally supported unless specified. The project uses the MIT License and cautions that extracting assets without appropriate rights may violate copyrights or software licenses.
Good
- Captures and replays Vulkan on four listed platforms.
- Includes Direct3D 12 capture and replay for Windows.
- Replay can run without the originating application.
- Includes compression and SPIR-V tools.
- Free and MIT-licensed.
Watch out
- Direct3D 12 support is listed for Windows only.
- OpenXR support is experimental and limited.
- Cross-operating-system replay is not generally supported.
Who it suits
GFXReconstruct is aimed at game and application developers, GPU and driver engineers, QA teams, hardware and platform teams, researchers, and tool builders. It may be useful when capturing or replaying graphics API calls for debugging, testing, analysis, or optimization.
Verdict
GFXReconstruct offers a broad set of graphics capture and replay tools, with Vulkan coverage across four platforms and narrower Direct3D 12 support. OpenXR and cross-operating-system replay have stated limitations, so check those details against the intended workflow.
