Adaptive Sync—Variable Refresh Rate

Adaptive Sync is the VESA standard for variable refresh rate displays. This display controller and display feature enables a better experience for the user by reducing tearing and stuttering. Adaptive Sync may also reduce overall system power consumption. Basic requirements for Adaptive Sync are:
  • Full screen rendering by the game or 3D application
  • Simple application swap chain modification to ensure asynchronous buffer flips
  • A DisplayPort 1.4 VESA Adaptive Sync capable display panel
  • Windows® 10 RS5 and beyond
The game or 3D application must ensure that its rendering swap chain implements asynchronous buffer flips. On displays that support Adaptive Sync, this results in smooth interactive rendering, with the display refresh dynamically synchronized with the asynchronous swap chain flips. If application and platform conditions are met, the Xᵉ-LP driver enables Adaptive Sync by default. There is also an option to disable it using the Intel graphics control panel. For more information on enabling Adaptive Sync, please refer to Enabling Intel® Adaptive Sync guide.
