Brodual's review of ICAIO mentions that it does not touch stealth behavior and recommends Immersive Detection of NPCs. However, IDNPCs is on the Dangerous Mods list. Some alternatives are Realistic AI Detection, Dynamic Stealth (download), and Detection Extended in order from least taxing to most taxing on your system, though Detection Extended can be heavily customized via MCM to be much less taxing than the default. Realistic AI Detection is a game-settings-only mod. This makes it very efficient, and highly compatible, but also seems to make it less dynamic. The author has released 4 different versions to try to accommodate different lighting and weather mod setups, but warns that it may not work as expected with certain weather or lighting mods. Dynamic Stealth is still beta, and the author is rumored to be working on a new version, but the present version has some bugs that cause inconsistent behavior. SRLE LotD does not seem to have anything addressing NPC detection (especially for stealth/light/sound). If I've missed something that does address this, please point it out to me. Has anyone used one of these mods, or a similar alternative with SRLE LotD? Do you have any thoughts or recommendations? [edited to add download link for Dynamic Stealth]
