How to run Fallout 4 at 144Hz
Just cap it at 60fps, guys. The game wasn't designed for 144Hz, and trying to force it can cause more trouble than it's worth. Enjoy the game as it was meant to be played!

Getting Fallout 4 to run at 144Hz is a bit tricky since the game's engine ties physics to framerate, causing issues above 60fps. First, make sure your monitor is set to 144Hz in your display settings. Then, you gotta open the Fallout4Prefs.ini file located in Documents\My Games\Fallout4. Add the line "iPresentInterval=0" under the [Display] section to disable VSync. Next, you might need to limit your FPS to just below 144 (try 142 or 143) using GPU software like NVIDIA Control Panel or AMD Radeon Settings to prevent physics bugs. Remember, messing with game files can lead to unexpected behavior, so proceed with caution!
I managed to get Fallout 4 running smoothly at 144Hz by tweaking the .ini files as mentioned, but also made sure my GPU settings were optimized for Performance. It took a bit of fiddling, but the difference is night and day. Make sure to backup your files before you start tweaking!
