📋 About This Mod
I have had a lot of trouble trying to get fallout 4 to run on my computer with a small bit of tweaking in the prefs file i was able to get it to run pretty smoothly where i went from 11 fps to about 40 on average i did find these setting out on a video and i did not make them myself i`m just posting so others can use it easy just copy it in your prefs
to install go to documents- my games- fallout 4- then copy and past Fallout4Prefs.ini
also with these settings you have to run it in a window due to the fact the resolution has changed sorry for not mentioning this earlier but i did not have this problem because i normally run it in a window
you also need to change the graphics to what you are using on your pc
this is the first file i ever uploaded so im pretty new to this and will help in any way i know how and i will read the comments
