Do you have anything in the "Vis" folder inside of Fallout 4 / Data? If your "Vis" folder has something in it, try to move everything out temporarily, just to see if your problem goes away. (The content in Vis folder is "Visibility" data. You might have some leftover data from removing a mod - removing a .esp only won't fix this problem.)
Your problem reminds me of what happened when I generated visibility without knowing what it actually does (lol).
Might also want to at least temporarily remove Data/meshes/Precombined. That, along with Vis, is all the mod or locally added precombine/previsibility data.
As for bUsePreculled, that determines whether or not the game respects preculling, i.e. the combination of precombine and previsibility. It is usually set to zero by scrapping mods to allow you to scrap things you otherwise wouldn't be able to because they potentially break precombines. So (yeah, longshot here) if you could figure out which of your mods changed that setting in your INI file you'd know which one was causing the problem.
Ah, another thing to look for. Some mods, for reasons I can't understand, clone your INI files and create their own version in your Data directory. Start Me Up does, Scrap Everything, a few more. Problem is those clones are full of settings they have no business touching. Like the path to your saved games, which screws up Vortex profiles badly.
You might still have bUsePreculled buried in one of them. Take a look, and remove the line if you find it. Don't set it to 1, remove it.
