Did you ever fix this on your setup? This many years later and I still haven't found a fix for this. I'm pretty close to just dropping the game completely. I've tried many different mod setups, every single tweak/setting/mod from many different forums, yet the LOD bug persists. My PC can run most other games on ultra settings with at least 60 fps. It's not the hardware. It's also not a mod issue, because it happens to me in vanilla too. The LOD bug makes it unplayable. Sometimes reloading a save refreshes the textures, but sometimes it doesn't. I love Fallout 4, there really isn't anything like it. That being said, as much as I love it, I hate constantly looking at LOD textures up close even more.
