PresentMon

What PresentMon is

PresentMon is a free Windows toolset for capturing and analyzing performance in graphics applications. It traces CPU, GPU, and display frame durations and latencies in DirectX, OpenGL, and Vulkan applications. The console application sends captured data to the console or CSV files, while the Capture Application displays live graphs and readouts in an overlay and can record per-frame CSV data. PresentMon combines ETW frame data with hardware telemetry such as GPU temperature and power. Client applications can access service data through its API and SDK; listed telemetry paths include ADL, NVAPI/NVML, IGCL, and WMI. PresentMon supports Windows desktop and UWP applications and is MIT-licensed software provided without warranty. Use requires membership in the Windows Performance Log Users group. Administrator privileges are needed for complete process information across user accounts and for short-lived processes. The project notes that some OpenGL and Vulkan CPU measurements can be less accurate, and GPU execution metrics may be less accurate when Hardware-Accelerated GPU Scheduling is enabled.
