Possible cause of infinite load screens/CTD

This link is for Skyrim, but still applies to FO4:

tl;dr There is a limit to the number of references that can be loaded into memory. Running a lot of mods that add objects to the game that make heavy world edits or add large numbers of cells that are not master files seems to be the cause of infinite load screens/CTDs. You can run this script in xEdit (FO4Edit) to see if you are exceeding this limit.

The other interesting bit is that even temporary references in esps are persistent in memory and count toward the limit of loaded references.

That’s an interesting read , to me it seems like some basic engine level reworks would be needed to fix it maybe ? I read a little about turning esp’s into esm’s can help but with a hard limit of 1050000 roughly refs until game is broke would really limit the amount of large mods that can be used. I’m guessing texture overhauls are not loaded in a way that counts against this. Then again I’ve seen people run Skyrim with like 600 mods by doing some merging so idk but would be interesting to see if anybody could implement an engine level fix for this in something similar to a mod or DDL file or something.

Generally, this only applies to people running a lot of mods like overhauls. The limit is REFR records in esps. For FO4 this is 2 million(ish)

For example, yesterday Whisper said when he esm-flagged Clean My Settlement in test, the script dropped references by about 150k You would need a lot of mods of this type loaded before you got to the 2 million(ish) limit.

Well hopefully they have taken this into account when redesigning their engine for starfield and beyond.
