Intel has released PresentMon 2.6.0, a major update to its free and open source performance monitoring software that reduces CPU overhead and expands the tool's frame analysis and telemetry capabilities.
The new version is designed to make PresentMon less demanding while it runs in the background. Intel says CPU usage can fall by as much as 78% compared with the previous release, including on mobile class systems.
PresentMon 2.6.0 also introduces a new Game Experience overlay preset aimed at showing metrics that better reflect how smooth motion and animation actually appear during gameplay.
| PresentMon 2.6.0 change | What it adds |
|---|---|
| CPU overhead reduction | Up to 78% lower CPU usage |
| New overlay | Game Experience preset |
| Metric handling | Unavailable metrics remain visible with explanations |
| Multi GPU support | Telemetry from multiple graphics adapters at once |
| DirectX 12 analysis | PSO compilation count, duration, and busy percentage |
| Frame data | Completed and dropped flip reporting |
| Display data | Additional display metadata |
| Availability | Free and open source |
Lower CPU overhead is one of the biggest changes
PresentMon tracks and records graphics performance, which means the monitoring tool itself consumes some system resources.
Intel says version 2.6.0 reduces that impact by changing how background operations are scheduled.
The software now uses less aggressive timing for ETW flushing and related tasks when precise timing is not required.
Diagnostic log flushing has also been adjusted to reduce CPU activity while the software is idle.
Together, these changes can reduce PresentMon's CPU usage by up to 78%.
That reduction could be particularly useful when benchmarking lower power systems or laptops, where the monitoring software's own overhead can have a more noticeable impact.
Game Experience overlay focuses on perceived smoothness
Another major addition is the Game Experience preset for PresentMon's overlay.
Rather than concentrating only on traditional figures such as frame rate and GPU utilization, the new preset highlights measurements that Intel says are more closely linked with perceived motion and animation quality.
The idea is to provide more information about how smooth a game actually looks, rather than relying on a single FPS number.
This could be useful when comparing games or graphics settings that report similar average frame rates but still feel different during motion.
Intel has not provided a complete list of the new Game Experience metrics in the supplied material.
PresentMon now explains unavailable metrics
Version 2.6.0 also changes how the application handles measurements that cannot be collected on a particular system.
Previously unavailable metrics are now kept visible in the interface and marked as unavailable.
PresentMon can also provide information explaining why a particular measurement cannot be used.
That should make it easier to distinguish between a missing feature, unsupported hardware, or another telemetry limitation without assuming the application has failed to detect the metric.
Multiple graphics adapters can be monitored together
The update also expands support for systems with more than one GPU.
PresentMon 2.6.0 can display telemetry from multiple graphics adapters simultaneously.
This could be useful on laptops and desktops that include both integrated and discrete graphics, as well as test systems using several GPUs.
Instead of focusing on only one adapter at a time, developers and hardware testers can inspect data from multiple graphics devices through the same application.
DirectX 12 developers get PSO compilation metrics
PresentMon 2.6.0 adds more detailed tools for DirectX 12 development and performance testing.
The software can now track Pipeline State Object compilation.
The available PSO measurements include compilation count, compilation duration, and the percentage of time spent busy with compilation.
These metrics can help developers identify periods where shader or pipeline compilation contributes to performance problems.
Pipeline compilation behavior has become an important area of analysis for PC games, particularly when investigating stuttering or inconsistent frame delivery.
Frame reporting and display metadata are expanded
The update also includes support for newer Windows DDI flip events.
PresentMon can now report completed and dropped flips, adding more detail to its frame capture data.
Additional display metadata has been included as well.
Combined with the new PSO information and Game Experience overlay, these changes expand PresentMon beyond straightforward FPS monitoring and give developers and testers more information about what is happening throughout the rendering and display pipeline.
PresentMon becomes lighter while collecting more data
PresentMon 2.6.0 combines performance optimization with a broader set of monitoring features.
The reduction in CPU overhead is especially important for a performance analysis utility because the tool itself should interfere with test results as little as possible.
At the same time, the new Game Experience preset, multi GPU telemetry, PSO compilation measurements, flip reporting, and additional display information give developers and hardware testers more data to work with.
The update remains free and open source, making the new capabilities available without requiring paid monitoring software.
