VSync - On or Off?

I don't even know what Screen Tearing is. :|

But 100% of the time VSync is off.

Depends on the game. Some games, vsync is necessary because they tear too much otherwise, other games it increases input lag to an unbearable state and I need to keep it off.

Personally I game on a 120hz monitor most of the time, keep everything fast paced there. It's usually only the bad ports that have a limited frame rate that I have to turn vsync on.

It's always turned off. Well, my computer is kinda old, so most of the game are hardware-caped to12-15 fps anyway...

I like to V-Sync because there is no need to output more frames than your monitor can display, more to the point, why would you want to? I like this discussion by the way.
