Vsync off can sometimes produce tearing, but I find this preferable to vsync on, which eliminates tearing but introduces latency.

Edit: Freesync/G-sync is an attempt to eliminate tearing AND latency. Unfortunately, this often requires a higher response time on many monitors. For example, on my simracing setup with a Samsung CHG90[1], you can't both enable freesync and the fastest response time on the monitor. I opt for the faster response time as it just feels faster and most of the time I don't notice the tearing.
