i see nothing about freesync there
DISPLAY=:0 xrandr --output DisplayPort-2 --set "freesync" 1
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 11 (RRQueryOutputProperty)
Serial number of failed request: 45
Current serial number in output stream: 45
well i dont know what to do about that. my ps3 controllers arent setup in windows for me to play to see what freesycn even does in a game. linux shows no info about whether it works or not.
