i just had to do it, because i am a Fallout76 fan, and i hate seeing negative reviews from ppls with content like "blurry as shid" or "drunk picture" or "ugly and choppy". mainly also i have a quick link now for myself, when helping noobs with the game.

• Navigate to your 'Documents\My Games\Fallout 76' folder and open the file Fallout76Prefs.ini in Editor.
  
  
• Press CTRL+F and search for iPresentInterval.
  
  
• if you found it, change it from 1 to 0, it should look like this when finished:
  iPresentInterval=0
  
  
• if you DIDNT found it, you have to add it manually under the [Display] header.
  
  addon for crisp clear textures:
  
  
• Press CTRL+F and search for iMaxAnisotropy.
  
  
• if you found it, change it to 16, it should look like this when finished: iMaxAnisotropy=16

You can modify your game even more for more FPS and less GPU-usage, but for that you have to create a File named Fallout76Custom.ini in the game folder. It will then automatically be copied by the game into the documents/myGames/Fallout76 folder, when you start the game.

here i added my Fallout76Custom.ini contents which remove blurring, grass and some other effects which started to ennoy me, as well as adding faster loading times.
