FreeSync, or Adaptive Sync, is a form of monitor refresh rate created by NVIDIA’s direct competitor, AMD. Much like G-Sync and V-Sync, the technology eliminates any form of screen tearing in all games via a dedicated AMD Radeon GPU.
But that’s where the differences between the two technologies end. Unlike FreeSync, NVIDIA’s G-Sync is proprietary; for a monitor to make full use of it, manufacturers are required to install NVIDIA’s G-Sync modules into said displays. They also have to pay a licensing fee to NVIDIA, which is basically why almost all G-Sync monitors cost an arm and a leg.
