Open Capture and Analytics Tool (OCAT)

Open Capture and Analytics Tool (OCAT) is a Windows utility for viewing frame-rate information and measuring graphics performance. It is intended for users who need performance information while working with applications that use supported graphics technologies. The tool provides this information through an FPS overlay and performance measurement functions. Its focus is on observing performance in software that uses D3D11, D3D12, or Vulkan.

The FPS overlay places frame-rate information where it can be viewed while the relevant application is running. Performance measurement gives users a way to examine how an application performs rather than relying only on visual impressions. OCAT therefore fits tasks involving graphics performance observation and comparison. Its documented graphics API coverage includes Direct3D 11, Direct3D 12, and Vulkan.

OCAT is distributed for the Windows platform and uses an open-source license. Its category is defined by its role as a graphics performance and frame-rate analysis tool rather than a general-purpose utility. MirrorNest mirrors the official OCAT build directly on its own storage. Before publishing the mirrored file, MirrorNest scans it for malware, giving downloaders a catalog copy that has passed that stated check.
