How to disable vertical sync in Fallout 4: instruction

Vertical synchronization is designed to make the image in computer games look smoother. However, this technology not only improves the quality of graphics, but also uses a lot of computer resources. In some games, there is a serious decrease in performance when this feature is turned on. Also, when synchronization is enabled, compatibility issues may occur. Let's figure out how to disable vertical sync in Fallout 4.

All ways

There are two ways to disconnect, but all of them are not related to graphics settings inside the game itself. To do this, you must use either the proprietary NVIDIA control panel, or editing game files. Let's consider both ways.

NVIDIA Panel

This option disables vertical sync through the driver settings. You can turn off the option both on the entire computer and on a separate game. To disable vertical sync in Fallout 4, do the following:

1. Launch the control panel of the video card.
2. Open the "Manage 3D Settings" subsection.
3. Go to the "Software Settings" tab and select the name of the game from the list.
4. In the table with the graphics settings, find "Vertical Clock" and select "Off."

Now you know how to disable synchronization in Fallout 4 using the video driver. Consider the second method.

File change

First you need to find a configuration file called Fallout4Prefs.ini. It is located in the same place where the game saves - in the "Windows Documents". Open this directory and find the folder "My Games", and in it a directory with the name of the game.

In it, find the mentioned document and open it through the standard Notepad. This can be done using the right-click context menu.

In the window you need to find the line "iPresentInteral-1". For convenience, use the search key combination Ctrl + F and paste the name of the line. Change the number 1 to 0 and save the change to a file. Now you need to go into the properties of the documents and in the "General" tab, check the box next to "Read-only". Save the changes again and close the properties window. The same thing needs to be done with another file called Fallout4.ini. It is located in the same folder.

Result

Now you can turn off vertical sync in Fallout 4 in two different ways. So you can increase the performance in the game by about 10-20 FPS depending on the power of the computer. However, twitching of the image with dynamic gameplay may occur along with this.
