Use Adaptive Sync with your Mac
Adaptive Sync is a technology that allows a display to adjust its refresh rate to match the frame rate of content rendered by the GPU. When you’re playing a video game on Mac and connected to a supported display, you can use Adaptive Sync to minimise screen tearing and input lag (a delay in the responsiveness of the display).
On your Mac, choose Apple menu
, then click Display Settings.Select your display in the sidebar, then click the Refresh Rate pop-up menu to see refresh rate options for the display.
Choose a variable resolution option for the display. The specific hz-hz range is determined by your display.
When not gaming or using a display that’s not validated, Adaptive Sync may cause the screen to flicker.
