How do I make Nier run smoother?

You can download and install the newest version of Borderless Gaming. If you want to play the game in a windowed mode, launch Borderless Gaming. Make sure you have a resolution that is at least 1920x1080p on your screen. Press Alt+Tab to switch to the Borderless Gaming window, and then choose the Nier: Automata in the "Applications" field.
