OCAT 1.2 Released with New Settings, Visualization Tool, and More

Okay, I will admit this one might not be of too great of interest to some of you, but I still want to share it because it will impact at least my reviews going forward. Today a new version of OCAT, the Open Capture and Analysis Tool from AMD was released. In simplest terms, it is a rather convenient front-end for PresentMon, a tool for capturing detailed frame time data, but is not the easiest to work with. Now with version 1.2, OCAT offers much more including support for VR/AR/MR head mounted displays (HMDs), data visualization, and system information.

Besides capturing frame time data, OCAT also offers a performance overlay, and now this can be shown on an HMD. It will also catch runtime-specific information for HTC Vive, Oculus Rift, and Windows Mixed Reality Platforms, such as warp misses.

The addition that might be the most interesting for most people though would be the visualization tool. This allows you to open up one of the output CSV files within OCAT and have it display a graph of the msbetweenpresent data. You can then open up additional files to show multiple datasets at the same time while you pan around and zoom in on the data. You can then save the graph as a PDF if you wish, though I think personally I will stick to my current graph-making process.

The addition of system information is nice, as it will record some configuration information in the summary file, such as CPU, GPU, driver, and even clock speeds for the GPU. Unfortunately it appears to only report the maximum clock speeds for the GPU, and does not represent what your graphics card was doing while capturing data.

Other changes include the ability to delay when the recording starts, setting the detail level of the output (likely following PresentMon's simple, normal, and verbose levels). You can learn more about the changes by following the changelog link below and you can download it through the project's GitHub page.
