Run With Switches

Exit any running-instance of Chrome.

Right-click on your “Chrome” shortcut.
Choose properties.
At the end of your “Target:” line adds the command-line switch. For example:
--disable-gpu-vsync

With that example flag, it should look like below (replacing --disable-gpu-vsync with any other command-line switch you want to use):

chrome.exe --disable-gpu-vsync

Launch Chrome like normal with the shortcut.
