Final Step:

• Save the file. Don't check read only if you want to customize setting in-game!
  
  
• If you want to unlock fps by disabling Vsync you can edit the line "iPresentInterval=1" inside the ini file and change the 1 with a 0.
  
  
• If you unlock fps make sure to cap your frames with your graphic card software to whatever you desire after that because you will face engine bugs. In short if you can't move your character (know engine bug for unlocking frames) then lower down the fps cap.

You are ready to play!

IMPORTANT NOTE:

• You can also change your resolution in-game, and you can touch most setting in-game besides the obvious that will override my settings like shadows, textures, lights etc..

EXTRA NOTE: (If you want to enable some SFX again)

• If you don't like effects like Sao, Volumetric lighting disabled or you think you can handle that, you can enable them again but this are very demanding effects specially volumetric lightning. It can be enabled by changing this lines from 0 to this values:

bVolumetricLightingEnable=1 (high perfomance impact)

iVolumetricLightingTextureQuality=1 or 2 for better quality (high perfomance impact)

bSAOEnable=1 (medium perfomance impact)

For old hardware users:

• If you really need more frames or lack enough memory on your graphic card besides using medium textures you can also put shadows in 1K, but note that shadows will look really ugly, you are advised. If needed then change the line iShadowMapResolution to this value below:

iShadowMapResolution=1024

AMD users "molerat complex" bug, aka character sink on terrain

• To fix this its also very simple just go to your Radeon settings sofware go to Fallout 76 profile scroll down and in tesellation select "override" and pick x16 option. ENJOY

I did this changes based on my F4 settings and hours of testing in fallout 76, this not only removes drops but also gives a huge gain in frames without losing visual quality, from 49 fps to more than 100 was my gain and i only have a modest RX 480 with 8GB, so give it a try :)

Enjoy

Not sure if this is just not valid anymore, but enabling these absolutely tanked my performance. Might just be one or two lines that just don't work with all the updates

[Jill sandwich]

@Ragna Probably 1 means activated thats why in 2 it doesn't change anything. Some settings instead of quality are either activated or off. As of what those lines do, it gives better performance reducing the quality of far away textures (mipmaps). In ultra its turned off with "0" so you get the better quality there without any reduced size.

Glad my config help you by the way, and yeah if you mess too much with the settings bugs like invisible waters and some other stuff can happen, you are mostly free to test my values with higher ones though, but less values will very likely give you bugs, since i tested my ini settings to be the minimun possible required to avoid bugs like that one you mentioned and similar.

[Ragna]

i just tested how ugly i can make the game lowerig setting for fun and for some reason when i put ShadowDistance and dirshadowDistance less tan 3k the water just gone xD

anyways amazig guide. thanks

also i noticed the "low texture settings" almost every texture the "1" in setting is a "2" but if i icrease the texture resolution it looks the same with the "1" the settings, any idea what does that number do?

iLargeTextureArrayMipSkip=2
iTextureMipSkipBC1UNormSrgb=2
iTextureMipSkipBC3UNormSrgb=2
iTextureMipSkipBC1UNorm=2
iTextureMipSkipBC5SNorm=2
iTextureMipSkipBC4UNorm=2

@Velonex said: "I have a 3080. After replacing my ini with yours I can no longer move my character."

It because you got 160+ fps. You need to cap it to 120-144, you can test it at your own.

[Breaded Chicken]

just wondering when you say high end pcs is it the highest quality it can go?

[Appleshark]

I was using everything on low and had 60-70 fps outside of the vault. When using this, it went to 170+ fps. Incredible!

[Synthydy]

I have tried all of these including messing with the nividia settings but still get a significant stutter and frame drop with cell loading. has anyone found a fix for this

[Foxy Demon Aura]

I would add a section about changing anti-aliasing in this as well.

[Last Stand]

@Velonex Did you try to cap your fps with your nvidia? This game has to be run under 100 fps or there will be bugs like your characters cant move.

[Jill sandwich]

@Velonex Thats weird.. because I tested my ini with the last update even on a clean game install and everything worked fine.

So the only thing i can suggest you is to delete both ini in "Documents/My Games/fallout76" delete fallout76.ini and fallout76prefs.ini and launch the game, let the game create the default files, exit, and after that paste my ini again. Launch the game and it should work.
