HWiNFO64 starting with version 7.63 will integrate PresentMon.
PresentMon is a component that captures and analyzes various events related to graphics presentation. It's primary role is to retrieve metrics like Framerate (FPS), Frame Time (ms) and GPU Busy.

Some notes:
- This feature is currently in Beta stage, so some issues or adjusting is expected.
- PresentMon is fully integrated into HWiNFO64 so there are no additional prerequisites required (e.g. no need to install Intel PresentMon or its SDK).
Statistics data are shown under a new sensor. - Integration into HWiNFO32 is currently not planned due to certain restrictions in legacy 32-bit applications
- PresentMon constantly captures and analyzes a large amount of data for each process (and its swap chain) that performs graphics output via interfaces like D3D9 or DXGI.
- Since each process/swap chain has its own metrics, the application needs to focus only on the "main" one. HWiNFO by default reports metrics belonging to the process with highest frame rate.
It's possible to specify a specific process to be monitored using the "-pm_proc_name=<process_name>" command-line argument. - The evaluation of frame data requires keeping statistics for last-n frames and perform constant calculations (averaging, etc.), which can have some impact on performance.
To minimize the performance and memory footprint impact of frame evaluation, HWiNFO currently keeps a fixed amount of last n-frames. - The metrics reported are calculated as an average of last-n statistics data over a certain time-window. A too small window means less math but also less accuracy due to less samples being averaged, a too large window might not properly reflect variable rates.
- The evaluation time window is currently fixed to a reasonable value. It is planned to allow users to use a custom time window, but matching it with the main polling sensors period might be undesirable.
- This feature can be disabled via main settings.
