Open Capture and Analytics Tool (OCAT)

The Open Capture and Analytics Tool (OCAT), developed by Advanced Micro Devices, Inc., is a lightweight benchmarking utility designed to provide real-time frame-rate overlay and detailed performance measurement for applications running on DirectX 11, DirectX 12, and Vulkan graphics APIs. Targeted at game developers, hardware reviewers, and performance enthusiasts, OCAT captures frame-time data with minimal overhead, generating precise logs that can be exported to CSV or JSON for downstream analysis in spreadsheets or visualization tools. The software’s unobtrusive on-screen display shows instantaneous FPS while a background recorder tracks every frame’s presentation time, allowing users to identify stutters, drops, and spikes that average counters often mask. Since its initial release the program has evolved through four public versions, culminating in the current 1.6.3 build that refines API detection, improves multi-GPU compatibility, and streamlines the session-management interface. Typical use cases include evaluating the impact of driver updates, comparing optimization techniques across rendering backends, and verifying consistent performance on heterogeneous hardware configurations. As a specialized diagnostics utility, OCAT belongs to the broader system-analysis and benchmarking category, complementing more general monitor tools by focusing exclusively on graphics-centric metrics. The executable is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, ensuring the latest version is always fetched and enabling batch installation alongside other applications.
