With the May 2019 update, Microsoft adds new features and a redesigned look, as well as minor enhancements to Windows 10 (1903) . Including the support for variable refresh rates (variable refresh rate, VRR).
This should support legacy games that do not support Nvidia’s G-Sync, or the VESA Adaptive Sync standard that AMD’s FreeSync builds on, with TFTs now also offering variable frame rates.
The background to this is that games in the UWP version for the Windows Store Adaptive Sync have so far not supported natively – as opposed to a common Win32 application.

VRR in Windows Settings
Anyone who has already switched to Windows 1903 can turn on Windows Settings VRR. Full-screen games for DirectX11 which so far did not natively support image synchronization technology, should still benefit from the technology.
The VRR option appears only if the following prerequisites are met:
- Windows version 1903 or later (Windows Insider Program )
- G-Sync or Adaptive Sync / FreeSync-enabled monitor
- Video card with WDDM 2.6 or later driver supporting G-Sync / Adaptive Sync and VRR option

UWP as culprit?
However, the feature does not seem to be disinterested: the Microsoft Store has been the subject of much criticism, including the (1945) Universal Windows Platform (UWP) interface, and even V for its compatibility issues -Sync (vertical synchronization) had some difficulties for UWP.
Although Microsoft complements the support for image synchronization, the developers must also explicitly include the support for this in their games (UWP version).
The dominant Win32 interface can VRR natively – meanwhile, Microsoft has also announced that the store is extended to Win32 support, but does not connect itself.
