In a few games (Osmos and Batman Arkham City are examples) there's a vsync item on the video options menu, but I don't know what it does and don't notice any differences when it is on or off.
What is vsync? What does it do?

Vsync stands for Vertical synchronization and is used to get rid of tearing in games.
Tearing happens when your GPU sends a new frame to your screen, while it is still displaying an older frame. Vsync tries to mitigate the issue by only sending a new frame, when your screen has finished displaying the older frame.
