First off, sorry for reposting this thread, I prematurely selected the best answer in this thread (http://www.tomshardware.com/answers/id-3243764/fallout-lag-high-end-gpu.html)

My Fallout 4 constantly dropping to as low as 15fps. This problem is incredibly annoying as I have just purchased a new MSI GTX 1070 Gaming X. My specs surpass the recommended specs for the game yet I still get constant lag, even on medium-low settings with god rays and shadows disabled. Apparently, this problem is commonly caused by a CPU that is bottlenecking the performance. What is wrong with my specs?

[I have tried downgrading my video drivers to no result]

Here are my specs:

CPU: Intel i5-6600
Mobo: ASRock H170M-Pro4
RAM: G.Skill Ripjaws V F4-2133C15d 8GB (2x4gb)
OS: Windows 10
 
This weird because I just started playing a heavily modded FO4 on ultra with the exact same card and a 6600K and I've been pulling a steady 60 the entire time. The only difference is that I have an extra 8 GB ram but I can't see that making a difference. Have you upgraded the GTX drivers? The reason I ask is that my card came with a disk with a bunch of MSI utilities but none of them were the actual Nvidia drivers or GForce Experience. I had to go to Nvidias website to download it manually.

*edit*
sorry, missed the part about downgrading the video drivers.
 
I see nothing wrong with your specs. I also have a 1070, but the laptop version (which is pretty much the same), and an i7-6700HQ (which I think compares to a high-end desktop i5) and 16 GB RAM. I don't get any FPS drops that drastic, although the framerate can go from 70+ to mid 30's depending on where I am in the game.

The one thing that I can think of that would lower your FPS that badly is if you have a high refresh rate monitor, because if you have a monitor over 60 Hz, the game halves the refresh rate. For example, my laptop has a 75 Hz display and Fallout 4 cuts it in half, to 38 FPS, unless I edit the config file. If I don't edit it, and I enable borderless windowed mode, it halves THAT to 18-19 FPS.

Oh, there is one thing I've noticed that is weird. Very rarely and randomly, upon moving the camera or shooting my gun, my FPS suddenly drops to 12-14 FPS and gets stuck there. It makes no sense at all, and my clocks are not being throttled or anything. All I can do is restart the game and it works fine. Maybe you have an extreme case of that?
 
I have a 60hx mon running in 1680*1050p. I have tried disabling vsync in the game's .ini file and using nvidia control panel instead and that did nothing. I have even tried vsync completely disabled and I get the same drops.
 
I just reset my bios and I am getting a solid 60fps on ultra with the occasional drop to 35 in some areas. :) Although I would be interested to know what it was that caused such low fps.
