I am absolutely open to any criticism people have about my knowledge. The guide has only grown since its launch, thanks to all those who have given their great insight and advice! If you find something that I could improve or correct, PLEASE tell me so I can either add, edit, or remove what you've mentioned. I want this guide to be the best it can be for a long time, so please let me know of new things! :]
If you're unsure, ask. I'll be happy to reply. However, most of my mods are custom made including my Raider Replacements, so if "custom mod" isn't the answer you're looking for then I'm very sorry kupo :(
Also here are the Discords which have armors and weapons that will definetly hold you over for awhile:
- ZARGE's Secret Lair
- FX's Discord, click the Discord Server button
- Ardent's Armory
- User Cerruti1889 for all the awesome settlement objects used in the screens, his work is on the servers above, so be sure to check them out!
Thanks to quote ALL modders
I have new PC and was confused that the game was running worse than it did on my old pc from six years ago. I was getting 60fps but with micro stuttering. Using your guide the micro stuttering has pretty much vanished. Realized it had something to do with light and shadows which your guide addresses. So, thank you for this guide once again.

That on the other hand WILL improve performance, in that if you have a lot of NPCs you don't get a lag spike when the engine tries to generate all their face data on the fly when you first load an area
If you want better draw distance fidelity, just follow the FOLIP instructions and generate your own LOD with TexGen, xLODgen and synthesis. Don't feck up your game by forcing it to load more cells than the engine is capable of. GamebryationEngine is a fickle mistress, and hell hath no fury like a Todd scorned.
It just works.
IMHO, I wouldn't recommend mods that remove objects for the sake of performance, as the objects use little to no VRAM or GPU power, your gains will be inconsequential. The only reason to remove things like all shrubs etc. is for aesthetics.
Even trash/leaf piles have their uses. Most of the time the devs used them to cover up mismatched terrain/gaps between building and floor where they don't mate perfectly or you can see into the void. So for ex. removing all trash in the game would make things look worse lol
Best way to improve your performance is good ol fashioned sliders in the game options menu / launcher. Or get a new graphics card. Do it.. buy a 4090 you peasants. Buy 2 and smash one of them. CONSUME. SPEND. OBEY.
My mod collection is hopeless. And cursed. And my hardware too...
Also maybe remove Long Loading Times Fix, it's known to cause textures to become blurry/low res after playing for about 10 or so minutes and I think it might be abandoned.
Ive had windows fight me when I try to change file type - as a workaround I just copy and rename the fallout ini and delete whats in it :)
