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 minimize screen tearing and input lag, a delay in the responsiveness of the display.
On your Mac, choose Apple menu
> System Settings, then click Displaysin the sidebar. (You may need to scroll down.)
Select your display, then click the pop-up menu next to “Refresh rate” 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.
If you’re not gaming or if you’re using a display that’s not validated, Adaptive Sync may cause the screen to flicker.
