Does anyone know which specific graphics setting controls how far away you can see Dews of Inspiration from?

I have to have all my graphics settings low because I'm on mobile, but I'm having the issue of not being able to see Dews of Inspiration until I'm basically on top of them. It's even making it hard to get ones I've already spotted if I need to back up and jump from a higher spot, because then I can see what I'm aiming for. So hoping I can just toggle a single graphics setting to a higher setting, at least temporarily if I'm having trouble getting a dew.
