How to Enable Variable Refresh Rate in Windows 10
Starting with May 2019 Update, Windows 10 comes with support for the variable refresh rate feature. Here is how to enable it.
Windows 10 version 1903 introduces variable refresh rate support (VRR). This feature is utilized by modern Store and UWP games to reduce screen tearing and get a higher frame rate.
A variable refresh rate (VRR) is a dynamic display refresh rate that can continuously vary on the fly. It requires a display that supports variable refresh rate technologies. Such display should support a specific range of refresh rates (e.g. from 20 Hertz to 180 Hertz). The VRR technologies change the refresh rate of the monitor in a game to prevent screen tearing. Variable refresh rate is similar to NVIDIA’s G-SYNC and VESA DisplayPort Adaptive-Sync.
For those curious why this is necessary, Microsoft Store games were initially not compatible with adaptive sync, and even had issues with custom V-Sync settings. Microsoft eventually rolled out support for these settings, but the developer needed to explicitly add support for it.
The new options enables variable refresh rate support for DirectX 11 games running fullscreen even they do not support VRR natively. This way, the games can benefit from your VRR-compatible hardware.
