Dude... holy s#*!.. I know this is a necro thread but this advice worked perfectly for me. I've got a GTX1080ti running a 4k monitor with a cheap second card running two 1920x1080 monitors. I have been struggling for MONTHS to get a stable framerate in Fallout 4 with the high rez texture pack installed Adding these two measly lines to my INI did it! I went from 50 fps with spikes down to 20 to a smooth 60 ALL THE TIME! You're my f****** hero

I know this is a necro thread but nobody here has posted the answer. This problem is caused by not launching with f04se. Double check to make sure you've got the latest version, that it's installed correctly, and that you're launch the game using the correct exe. If you don't know what f04se is, A) it's a script extender which is a requirement for many fallout 4 mods, and B) you should use your google fu to find out how to download, install, and operate it.

Same sort of thing happened to me just now. I think it was caused by uninstalling and reinstalling though NMM without admin. Kept reinstalling CBEE and nothing happened. Reinstalling CBBE base mod with admin privileges fixed the problem for me though.
