Fields

VerticalSyncRate

The refresh rate, also known as vertical sync rate, which controls how often the display pipeline scans out to a target. This rate is represented in Hertz (Hz) and stored as a two-part rational number.
VerticalSyncsPerPresentation

Specifies an integer divider to scale down the rate of full-screen presentations as a fraction of vertical syncs. For example, if VerticalSyncsPerPresentation is set to 2, then one full-screen presentation will last for 2 vertical syncs before the next presentation can occur. Support for values other than 1 requires hardware support.
