I think it's from JSRS Sound Mod www.nexusmods.com/fallout4/mods/52931 or Physics Impact Overhaul and Bullet Casing Sounds www.nexusmods.com/fallout4/mods/65489
ADS time or physical zoom magnification when in scope? The scroll zoom function in FTS is slow overall. Not sure how to change the zoom steps and that's the frameworks issue, not this patch. If it's slow ADS time its probably script lag from having too many mods that run scripts.
