Vsync, does disabling really do anything?

[Bo Lee]

OK, sure I know that if you disable Vsync your GPU can push out a lot more FPS. That being said, regardless of what your GPU is pushing, what you see is still limited by your monitor. I have a Sceptre LCD monitor that is just 60hz. So when I disable Vsync and go from 60FPS to 117FPS on a game, is there really any difference? Or would it likely only be noticeable on a newer monitor that is capable of 4k 240hz?

The advantage of VSync is that you get rid or limit screen tearing however input lag may increase. If you are playing super competitive games then I would leave it off.

Vsync not only increases the displayed latency by 33%, but if you drop below your monitor's refresh in fps, you will suddenly have your FPS cut in half. Vsync makes my mouse feel laggy. It's one of those things I forget about when running a game for the first time but quickly get annoyed by it enough to remember to disable it.
