Jonathan Schiller :
Screen tearing happens when your GPU is pushing to high or to low of frame for your display to show. As You are using Nvidia 10 series cards, I would suggest you disable the vsync in games, and enable the Nvidia Fast Sync from the Nvidia control panel. Vsync is an out of date setting anyway.
Tearing occurs when new frames are not sent during vertical blanking mode. It has nothing to do with your FPS.
And Fast Sync is much worse than regular V-sync in one critical way; it can cause a lot of stuttering. Fast Sync is meant for situations where you get massively high FPS and want to keep your latency as low as possible. CS:GO type games are its target and even then, many people don't like it for even that game. Fast Sync is a try and see type of thing. It certainly isn't for everyone, and definitely not to be set to on for all games, but in special situations, it can be a good thing.
