Laggy just because im holding a gun

[DeathknightDNOfficial]

First it was only the AMR, but suddenly its everywhere. I'm at Forlorn hope RN, but its been acting like this in plenty of other areas.
I just whip out a 9mm, service rifle, LMG, etc, and LAG, LAG EVERY WHICH WAY! FOR NO FORSEEABLE REASON - it just suddenly started happening and I have no clue how to fix it, please help, SoS, blah de dah, point made.

So, what changed?

 

In general, if you haven't changed anything about your game and it suddenly stops working correctly you need to look to other causes: such as software updates to Windows, programming libraries such as ".Net", or hardware drivers. Older games eventually get dropped from product testing. It is also possible you are having problems with your hard drive. It never hurts to run "chkdsk" and an anti-virus scan.

FYI: If you recently had a Windows system update, you only have 10 days to revert to the previous version if you decide to choose that option.

 

Frankly this sounds instead like you installed a mod affecting weapons, such as a "reload animation" plugin. "Lag" generally means your system is overtaxed and consuming too many CPU (main system) or GPU (graphics card) cycles. Please provide ALL the information requested in the wiki "How to ask for help" article. Don't forget to identify things that do not appear in the "load order", such as the version of Windows, if you are using a "Steam" or "GOG" and/or "regional language version" of the game (even if you are playing it in English); using the FNV4GB Patch, NVSE and it's related plugins; replacements for textures (specifically their larger image sizes: 1024x1024, etc.), animations, or "bodies", etc.; and "post-processors" like ENB or SweetFX. It saves us playing "20 questions" and gets you a more specific answer more quickly. (The usual turn-around on post and reply in an older game forum is 24 hours.) Screenshots of the "load order" don't usually work so well because they tend to cut off or fail to display needed information and are hard to "piece together" into a complete and coherent picture.

* See "How to markup images (etc) in forum posts and comments" article for how to use "Spoiler tags", etc.. "LOOT" already includes those tags in the "load order" it copies to your clipboard, so you can just paste it's list into your post.

So it was probably that update thing because I went to bed and windows needed to update, so let it update before going to bed, next day it was fine.
