Did you read the source? Vsync is off, windows is preventing the tearing. I only pasted what was listed in the chart.
It is possible to completely bypass control panel and in-game V-Sync options to utilize Windows’ native V-Sync implementation, which is also triple-buffered. By running the game in a window or borderless window, Windows handles the vertical synchronization, which can lead to smoother gameplay and lower input lag. Make sure you disable V-Sync in all other areas before doing so.
