If you don't know what you're talking about, learn from the people who know. There's a reason I say what I say. Don't you think I've sat down and tested it? It is PLAINLY visible if you lock your framerate to your refresh rate without using vsync that there's tearing. I've sat down with a good camera with a high shutter speed and done objective testing.
No vsync, 120 FPS cap:

Vsync, no FPS cap:

There's actually a slight blur to the vsync picture, but it does not tear like a non-vsynced image.
