Fallout 4 - Any performance recommendations?

[Dapoculos13]

Hi, I'm looking for any good methods of improving my overall performance in Fallout 4 on a low-end machine. I'm willing to try almost anything, including mods, code changes, file editing, etc.

 

VERY IMPORTANT NOTE PLEASE READ BEFORE POSTING: Do not bother telling me to upgrade my PC's hardware because I cannot afford it and do not know how. Also do not bother trying to tell me it won't work because Fallout 4 does work on my PC and I am looking for ways to improve on its performance.

 

My current rig is:

 

Intel Core 2 Quad Q6600 2.4ghz OC'd to 3.0ghz

Nvidia GTX 460 1GB NOT OC'd

4GB DDR2 RAM NOT OC'd

1TB HDD

ASUS 24 inch LED 1080p monitor 1920x1080 resolution

Windows 7 Ultimate x64

 

GPU details:

 

GPU Clock: 650mhz

Memory Clock: 1700mhz

Shader Clock: 1300mhz

Memory Type: GDDR5

Shaders: 336 Unified

Bus Width: 256-bit @ 108.8 GB/s

PCIe Interface: 2.0 @ 1.1x16

Driver Version: GeForce 358.91 WHQL

Speed: 1170-1200 rpm

ROPs: 32

 

I also have the Nvidia Control Panel and Nvidia Inspector to make further changes and tweaks if necessary.

 

Currently I am playing on fullscreen with all of my launcher settings at the lowest possible setting. I am primarily experiencing significant framerate drops upon moving the camera in certain directions, both third and first person. This is a complete vanilla install on Steam. In my first hour, I primarily maintained a framerate of roughly 60 at best and 20 at the very worst. My first hour primarily took place in Sanctuary Hills 2077, Vault 111, and Sanctuary Hills 2287. I also have Vsync disabled and FPS capped at 60 w/ Nvidia Inspector. I also edited the FOV and mouse movement to my liking, with additional code changes made to support mods. Nothing else has been done to my .ini files nor do I have any mods installed as of yet.

 

I would appreciate any help you can give me in any way, shape, or form.
