GameTechDev/PresentMon

PresentMon is a performance analysis tool that captures and analyzes the high-level performance characteristics of graphics applications on Windows.

The tool addresses the need to measure and understand graphics application performance by tracing key metrics including CPU, GPU, and display frame durations and latencies. It works across different graphics APIs such as DirectX, OpenGL, and Vulkan, supports various hardware configurations, and handles both desktop and UWP applications. The underlying approach uses Event Tracing for Windows (ETW) to collect frame events at a low level, combined with hardware telemetry from vendor APIs to gather metrics like GPU power, temperature, and utilization.

PresentMon is suited for developers and performance analysts who need detailed frame-level performance data for graphics applications. The tool offers multiple interfaces to match different workflows: a console application for collecting CSV data, a service that exposes performance data via an API, and a GUI capture application with real-time overlay graphs and per-frame data export. The README identifies several related tools in this space, including AMD OCAT, CapFrameX, NVIDIA FrameView, and others, indicating a mature ecosystem of graphics performance analysis options.

The project maintains an organized codebase with distinct components for collection and analysis, console access, service infrastructure, and user-facing applications. Documentation is structured with separate README files for each major component, and the repository includes contribution guidelines and build instructions for developers who want to extend or modify the tool.
