Yo! So, wanna tweak FPS in Fallout 4? Dive into the game's settings and hit up the display options. No luck? Time for the big guns: go edit the Fallout4Prefs.ini file located in your Documents/My Games/Fallout4 folder. Look for 'iPresentInterval=1' and change that 1 to 0 to unlock your FPS. Just a heads up, going limitless on FPS can sometimes make the game act all wonky because it's tied to the game's physics.
Actually, capping your FPS can avoid the havoc unlimited frames tend to cause in Fallout 4's world. Use a third-party tool like Nvidia Inspector or AMD Radeon software to set a max FPS. Keeps things smooth without breaking the space-time continuum.
