This page collects test results for Variable Refresh Rate (VRR) aka. adaptive sync setups seen in the wild.

To add an entry:

• Enable VRR on your display(s) via output <name> adaptive_sync on (see sway-output(5) for details)
• Make sure VRR is enabled with swaymsg -t get_outputs | jq '.[] | pick(.name, .adaptive_sync_status)'
• Play with your desktop for a while, try various apps (text editing, web browsing, video, games)
• Also play with the backlight level
• To get the VRR range, you can use: cat /sys/class/drm/card0-DP-1/edid | edid-decode (look for "Display Range Limits")
