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
in the sidebar. (You may need to scroll down.)Select your display on the right, 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.
