Man of Honour
Not entirely accurate, on a Gsync/VRR Gsync Compatible display, enabling Vsync has an alternative function as to how the VRR works and is necessary. Before later NV driver updates, Vsync was forced on when Gsync was enabled, because that's how it works. It should go back to that really and probably will with the new NV App once it hits release and replaces NVCP as NV mentioned the removal of defunct settings that don't matter any more.
