I've tried testing various combinations with vsync/enhanced sync & limiting fps to Hz-3 on both cyberpunk and valorant. No matter what, as soon as I turn on FreeSync I get little jitters/stutters with movement and in cyberpunk I even get an ~15 fps drop along with the jitters, which was surprising. I'm using an RX 6800 connected to two 144hz monitors.
Also, their recommended settings here: https://www.amd.com/en/technologies/free-sync-settings says "Use framerate cap at your own discretion" without any clarification to what that means...does it mean it's not necessary to cap? or that you should cap Hz-3? Afaik freesync isn't working if the game goes beyond 144 fps so idk...
As soon as I turn freesync and enhanced sync/vsync off, everything is high fps and smooth.
P.S. I have also tested with Anti-Lag ON/OFF.
