While going through Apocrypha, I noticed my FPS would sometimes drop significantly for no apparent reason when I was near Seekers. If I kill the Seeker, the FPS would go right back up again, which hinted at a script problem. I saved the game during one of those FPS drops, opened the save in ReSaver and noticed the issue - DLC2dunSeekerInvisScript.

This script controls the Seekers' ability to go invisible when they detect you, quickly close the distance and reappear right in front of you when you least expect them. The issue with this script is that as soon as the Seeker goes invisible, it will start spamming itself as quickly as the game will allow it and if the creature happens to not have a direct path to you, which is not uncommon for Apocrypha, it can unnecessarily highjack a lot of the game's scripting resources and slow it down to a crawl.

This mod optimizes the original implementation for better performance by replacing the inefficient while loop with periodic updates through RegisterForSingleUpdate, which will greatly reduce the stress on the system and not tank your FPS.




Install with your favourite mod manager. New game is not required, but it is preferable to install this while away from Apocrypha.




Not compatible with anything that changes the DLC2dunSeekerInvisScript script. USSEP changes have been retained.
Compatible with everything else.

No need to concern yourself with load order, as there is no ESP. However, due to the way the game loads its files, loose file mods like this one will always take priority over mods packed into BSA regardless where they load. If a mod happens to edit the same script and is packed into a BSA, this mod will overwrite it and potentially cause issues. Let me know of any such cases and I will make a patch to accommodate the relevant changes into this mod.
