The recently released action role-playing game, Fallout 4 has become extremely popular. It is available for PC and game consoles. On PC, it has a number of issues you might face. One of the issues is mouse lag. The mouse is not responsive for many users. Another issue is low frame rate. With my GeForce GTX 750 Ti, it gives only 30 FPS! Here is what you can do about it.
- Close the Fallout 4 game.
- Go to your game preferences folder. Usually it is located at:
This PC\Documents\My Games\Fallout4
If you are running Windows 7, go to
C:\Users\your user name\Documents\My Games\Fallout4
- Double click the file Fallout4Prefs.ini. It will be opened in Notepad:
- Find the line iPresentInterval=1
Change it to
This should fix the mouse lag issue.
- Find the line bForceIgnoreSmoothness=0
Change it to
If you are an NVIDIA SVGA card owner like me, try the following steps:
- Go to your Desktop, right click the NVIDIA icon in the system tray (notification area) near the clock. Open the NVIDIA control panel.
- Now go to "3D Settings" and add Fallout.exe to your Programs.
- Then, apply the following tweaks:
"Triple Buffer" to ON.
"Max frames render ahead" to 1.
And finally "V-Sync" on.
This should improve the game performance a lot.
