CyGPUInspector 0.1.0

First version of CyGPUInspector: a real-time and offline GPU inspector (frame debugger, shader and resource browser, profiler, decompiler, AI-assisted analysis) that uses ReShade's official add-on API as its capture agent inside the game process.

What is inside

Folder	Content
App/	CyGPUInspectorApp, the analysis application: frame timeline, frame graph, resources, shaders with multi-backend decompilation, deep capture that saves the final image and the frame's buffers (PNG and DDS), shader disabling and replacement, mod export. CyGPUInspectorMCP, a local MCP server, read only by default. Microsoft's DirectX Shader Compiler 1.9.2607, for Shader Model 6.
Addons/	CyGPUInspectorRS.addon64, the ReShade add-on that tracks and captures the frame. CyGPUInjector.addon64, which applies an exported mod without the rest of the tool.
Unreal/UE5.8/, Unreal/UE5.3/	The Unreal Engine plugin (UE5.8 build, and UE5.3 build for 5.3 to 5.7): captures the 3D render of the main viewport from the editor and from Development / DebugGame builds. ReShade 6.8.0 (full add-on build) is included in the plugin. Not loaded in Shipping builds.
TestWithoutAGame/	A fake session to try the application with no game at all (Demo.cmd), and the test suites.
Docs/	The documentation (French in Docs/fr/).
Licenses/	The licences of the third-party components shipped in the zip.

Requirements

• Windows 10 or 11, 64-bit.
• For a game: ReShade with full add-on support (reshade.me), D3D11 or D3D12. CyGPUInspector injects nothing itself: ReShade loads the add-on. A game that refuses ReShade is not supported, and nothing here tries to work around anti-cheat systems or protections.

Known limitations

• The frame is observed through ReShade's add-on API, not replayed.
• Pass names are derived: no graphics API exposes an application's debug markers to a ReShade add-on. Resource names are read when the application provides them (Unreal does, in the editor and in Development builds).
• The HLSL shown is a reconstruction, never the original source, and is labelled with the backend that produced it.

Details: Docs/Limitations.md.
