Many people, including me, cannot use Vsync / Freesymc // G-sync on >60Hz panel without fps hardlocked. I'm speaking for myself, and I'm others would agree with me, that an official working vsync option should be included in the game. I do not understand how a game this big has this kind of problem.

agreed as vsync will help keep the game alive and stabilize the fps as 5 years dowe the line when this game runs on a system too powerful for it and fps causes issues

They won't do it as once again, going over 60fps is messing the engine. It is not that bad as it was in Skyrim but still affect speed of lockpick for example.
