Intel PresentMon version 2.2 massively reduces event latency with metrics now being reported in real-time instead of being delayed by one second.
For those unaware, PresentMon is a free GPU monitoring tool from Intel that allows users to collect data and monitor performance in real-time through an integrated overlay. The tool is widely used by third-party software like CapFrameX, Frameview, or OCAT and works with third-party vendor GPUs as well.

The GPU enthusiast tool was last updated over a year ago, where we saw new metrics like GPU Busy added. Version 2.2 is the biggest update we’ve seen since then, introducing features such as; improved input latency, Click-to-photon metric, and reduced latency.
New Features
- Overhauled the ETW backend to reduce event latency from 1000ms => ~30ms; overlay now displays data instantly without 1 second lag
- Added a new click-to-photon metric that only tracks mouse button events; renamed previous click-to-photon metric to “all-input-to-photon”
- Improved input latency reporting so that input falling on dropped frames is attributed to the next displayed frame rather than being ignored
- Enabled the client to gather log data from the service and increased log coverage, particularly at the “debug” severity level
Bug Fixes
