Why don't all games suffer from screen tearing?

A quick Google search didn't bring me any obvious answers but seriously why is it with V-SYNC off in one game I could get 80fps and have no screen tearing....but then I play another with V-SYNC off and 80fps and tons of tearing...I know why tearing happens but why doesn't it happen to every game?
