Fort Collins, Colorado, United States
What it is
GFXReconstruct is a free, open-source toolkit for capturing and replaying graphics API activity. It records API calls, parameters, and state to a file, then can replay the capture without the application that produced it. The toolkit covers Vulkan and Direct3D 12. Vulkan capture and replay are listed for Windows, Linux, macOS, and Android; Direct3D 12 support is listed for Windows only. Repository tools include capture layers and libraries, replay, capture information, compression, SPIR-V extraction, conversion, and optimization. Listed uses include reproducing defects, examining API usage, performance profiling, regression testing, and platform bring-up. 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 apps, and absent from the SDK-built version. Cross-operating-system replay may work in some cases, but is not generally supported unless specified.
For and against
For
- Free and open source
- Captures and replays Vulkan and Direct3D 12 activity
- Vulkan support spans Windows, Linux, macOS, and Android
- Includes capture, replay, compression, and conversion tools
- Supports defect reproduction and regression testing
Against
- Direct3D 12 capture and replay are Windows-only
- OpenXR support is experimental and limited
- Cross-operating-system replay is not generally supported
The verdict
GFXReconstruct provides capture and replay tools for graphics API debugging and analysis. Its support differs by API, and OpenXR and cross-operating-system replay have stated limits.
Who it suits
GFXReconstruct may suit game and application developers, GPU and driver engineers, QA teams, platform teams, researchers, hardware vendors, and tool builders working with graphics APIs.
