Screen tearing is not really about whether a game is intensive or not. It's just when your FPS output from your GPU doesn't match the 60hz refresh rate your monitor provides. It won't do any damage if that is what you are worried about, although it is annoying. In some games you can turn on V-Sync to match the two but you may get a performance hit and in my experience it doesn't work perfectly anyway. I leave it off unless I have a problem with tearing.
Some, mostly more expensive screens use a version of V-Sync but only work with certain GPUs - G-Sync (Nvidia) and Freesync (AMD) They work well but as I said, more expensive, especially monitors with Nvidias G-Sync...
