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

If you recently purchased a Windows laptop, it is most likely equipped with a high refresh rate display. In terms of recent computer advancements, this is one of the more significant upgrades you can get because they help make every interaction, including scrolling, look and feel smoother. However, increasing the refresh rate of the notebook computer display is also a major battery drain.You can get the best of both worlds by manually switching between different refresh rates, but doing so is time-consuming, so Microsoft has introduced a project called Dynamic refresh rate (DRR) and the first Windows 11 Insider preview

As the name suggests, DRR will reduce the refresh rate of your notebook computer to 60Hz when you are writing emails and documents, and then increase it to 120Hz when writing and scrolling with ink, making these interactions feel more instantaneous. As of today, support for this feature is mainly limited to a few applications from Microsoft and Adobe​​e. For example, when you use inking and scrolling in Office, the refresh rate of your computer will increase to a faster refresh rate. However, Microsoft said that over time, more applications will support this feature. One thing to note is that DDR will not be turned on when you are playing games, so there is no need to worry about putting you at a disadvantage in a multiplayer competitive game.

To try DRR, you need a laptop with a display that supports a variable refresh rate of at least 120Hz. You also need a graphics driver that supports this feature. Therefore, even if you have a laptop that meets the above requirements, you may not be able to enable DRR after installing the first Windows 11 Insider version. This is a problem that Microsoft said it is working with manufacturers to resolve. However, if your laptop has the necessary driver support, you will find the option to turn on DRR in the system menu.
