Remarks
Starting with Windows 11, DisplayPresentationRate is virtualized if the physical display is capable of virtualizing refresh rates, and doesn't necessarily represent the actual pixel rate on the wire.
To determine the actual physical rate at which the display is scanning out pixels, use the flag DisplayManagerOptions::VirtualRefreshRateAware while creating your DisplayManager and DisplayPath objects.
If your application's DisplayManager isn't virtual refresh rate aware, then it won't be able to access PhysicalPresentationRate.
