OCAT 1.6

December 10, 2019

OCAT is our open source capture and analytics tool, designed to help game developers and performance analysts dig into the details of how the GPU presents finished frames to the display.

It runs in parallel with your game, sampling available DXGI presentation metrics, to give you an accurate view of frame timing, pacing, and delivery that’s as lightweight and unobtrusive as possible. Combined with an optional runtime overlay that lets you view the data in real-time as the game is running, OCAT is intended primarily for performance analysis, helping to discover and fix issues in frame pacing.

Changes in 1.6

This is a very small release with only one change – but a very important one! We added the option to disable the overlay during capture. OCAT’s overlay can have a noticeable overhead on some – mainly DX11-based – games. When the overlay is disabled during capture, this overhead is greatly reduced leading to more accurate results.

And as usual, several bug fixes also made it into 1.6, mainly fixing overlay compatibility issues with some games.

The documentation is visible at ReadTheDocs, we’re issue-driven as much as possible and welcome contributions in any form.
