The game must be forced to use the new resolution via its .ini config file.
Open the NVIDIA Control Panel , go to Change resolution > Customize , and create a new profile with 1400 horizontal pixels and 1050 vertical lines .
By slightly cutting the horizontal field of view (FOV), it forces more concentration on the center of the screen, which can benefit close-quarters "box fighting". Configuration Guide

A lower resolution typically results in reduced input delay , making building and editing feel more responsive and smooth.
