Nvidia LDAT & PCAT – What Are They?

What is FrameView 1.1

Having all this fancy hardware for recording latency and even power usage is one thing, but it needs to send that data somewhere. That’s where FrameView comes in, as it can handle the APIs from the testing hardware and provide a way to write that data into logs and summary files. The latest version 1.1 update addressed some issues too, as the software can now export data using FrameView Excel Analyser templates, allowing you to create charts and more to suit your needs; very handy for us reviewers!

What Can It Do?

The software can record CPU metrics, Render Present Latency, and other system parameters, making it a pretty potent tool for recording system performance. While you can run it on the system you are testing, it’s best to run FrameView on an external system for the latency testing, such as on a laptop, that way you’re capturing the information from the LDAT mouse and camera, without the test its self influencing the system performance.

What APIs Does it Support?

FrameView can capture data from all major APIs and virtually all games. It supports DirectX 9, 10, 11 and 12, OpenGL, Vulkan, and Universal Windows Platform (UWP) applications, and no doubt will continue to be updated should anything new come along. Of course, unlike the LDAT testing, measuring some aspects requires this software to be running on the machine you’re testing. Thankfully, the software is designed with a very small overhead, so it shouldn’t have too much impact, overall.

What’s new in Version 1.1?

• Logs and Summary files have been completely restructured based on user feedback. Summary files now contain references to each log file in that directory – making it truly a summary of the benchmarking session
• A new FrameView Excel Analyser template that consumes log files and automatically creates charts that can be stylized to the reviewer’s needs
• Vulkan Overlay support
• PCAT integration such that power metrics can be added to the logs directly from PCAT
• A new installer to make updating FrameView easy
• New metrics: CPU metrics, Render Present Latency, and system parameters
