Fast Sync is supported on Maxwell GPUs (GeForce 900 series) and up including the Pascal (GeForce 10 series) and Turing (GeForce 20 series) GPUs. Users can enable Fast Sync globally or on a per game basis through the NVIDIA Control Panel. Simply navigate to the Manage 3D settings section and enable Fast Sync through the Vertical sync drop down.
Note: If SLI or 3D Stereo is enabled, Fast Sync option will not be available. Fast Sync will be available once SLI or 3D Stereo is disabled.
