The Windows 11 preview can dynamically change your refresh rate to save battery

A high refresh rate display is a feature that Windows laptops may have recently acquired. It's one the most noticeable computer upgrades. They make all interactions, including scrolling, much smoother. However, turning up the refresh rate of your laptop's screen can also cause significant battery drain. Although you can have the best of both, manually switching between different refresh rates is time-consuming. Microsoft has introduced Dynamic Refresh Rate (DRR) in the first Windows 11 Insider preview.DRR, as the name implies, will reduce your laptop's refresh rate by 60Hz for writing documents and increase it to 120Hz for scrolling and inking. This makes interactions feel instantaneous. The feature is currently only supported by a few apps from Adobe and Microsoft. When you scroll in Office, for example, your computer's refresh speed will increase to a faster rate. Microsoft claims that the feature will be supported by more apps in the future. DDR will not turn on while you are playing a game. This means that you won't be at disadvantage in competitive multiplayer matches.DRR requires a laptop with a display that supports a variable refresh rate of 120Hz or more. A graphics driver must also be installed to support DRR. Even if your laptop meets these requirements, DRR may not work after you install the first Windows 11 Insider Build. Microsoft claims that it is working with manufacturers to resolve this issue. If your laptop supports driver support, DRR can be turned on in the Systems menu.
