To do this Go to Library --> Go to "New World Preview" --> Click Settings Icon --> Click Manage --> Browse Local Files. (see photo for guide)

This will bring you to this window: Just open the properties page of NewWorldLauncher by right clicking then click "Properties"

Finally, this will open up another window, Click "Compatibility" then click "Change High DPI Settings".
This will open another window. Select "Override high DPI scaling behavior" then in the dropdown select "Application". Click "Ok/Apply" on everything.

Your game should now look better. Hope this works for you. Please give the guide a rating so other people can see it as well. This is my first guide on anything so let me know how to improve, thanks! 😀
