Hello, I have a Dell S2721QS monitor and an NVIDIA 3060 Ti graphics card and I am interested in how to activate FreeSinc. G-sync option in NVIDIA drivers is ON, is it necessary to turn ON V-sync in games? I tested and only in that case I have no tiring. Also, I use the DP port and my screen response time is set to Fast (I have also Normal and Extreme options).
