now that is sound advice.
this does not apply to a few of us. we simply keep absolute minimum dip above 60fps.
so. what is better. freesync, gsync, adptivesync. or are they all the same.
Adaptive Sync == Freesync in most cases, Adapative Sync is the Display Port standard, which is used with AMD as "FreeSync" (FreeSync can also do HDMI on upcoming monitors).
GSync requires the expensive gsync module to be installed and is Nvidia only.
Nvidia doesn't support Adaptive Sync because they know they'd lose all sales of GSync monitors if they did (since people wouldn't pay the premium).
