Relevant settings are:

-refresh rate fixed to 60
So run ccsm on the xscreen where you see the tearing, that is if the tearing happens on your TV and you use the "separate x screen option" in nvidia-settings, run ccsm on that screen and enable "vsync to vblack" ("general options", then go to "display settings" tab)
I found this solution too, but for me with full screen opengl applications still have tearing (xbmc in my case) The tearing happens to be only on a specific height of the screen, like it was syncing to vblank, but in a wrong time (a little bit always delayed)
