Fallout 4 "hiccups" when NPCs aggro the player.

[ArmoredTroll]

Hey y'all, I've noticed a recent issue with Fallout 4 with the game freezing for about half a second whenever enemies or other NPCs aggro the player.

Here's my current load order.

I don't think the load order matters. I suspect it's part of the game engine itself.

I've noticed that if a couple of dozen enemies aggro at me at the same time, my game crashes. I've noticed this condition since at least 2016, so I'm pretty sure the game launched with this weakness.

For instance, back when the game was newer, I was setting up a screen shot where all the gunners in Vault 95 were around my character with time frozen. I made this mistake of saving my game like this *laughs*

So I fell into a crash loop where every time I unfroze time, the gunners would all attack at once, and I'd crash.

I got around it by turning on tcai (toggle combat artificial intelligence) and then getting out of their midst before restoring combat AI.

Basically, I try to avoid situations in which lots and lots of NPCs aggro against me at once. So long as I don't allow all of a cell's NPCs to see me at the same time, my game has remained stable without issues.

As I said, it's been this way as long as I can remember.

Oh wow, Nexus doesn't give me a notification that someone replied to my forum. So, sorry for only noticing your reply exactly a month later. Thanks, for the reply. But, it would hiccup from only a single enemy going aggro, so I don't think that was the cause. In any case, I've since started and completed another playthrough without issue, so I've wrote it off as a random "Bugthesda" bug.
