I'm in the middle of tweaking some stealth settings, and I wanted to increase the gap between Noticed and Detected so that sneaking would be less binary and enemies would be more prone to simply investigating your location rather than straight-out spotting you and initiating combat.
Problem is, I can't find any Gameplay Settings that govern this. I've found plenty that seemed like they should, but tweaking them even to extreme degrees has made no visible difference.
Does anyone happen to know what settings affect this?
