no setting like that. i see one called LOD distance (i think) maybe its that one?
I'm actually not as concerned anymore, it shows me the "big mobs" like the razor queen, at the very edge of radar, or even before they come into my radar, so if i see dots on my radar, and dont see a mob, most likely its not a big one.
(ofc everyone has their own definition of a big mob

) but im probably ok for now
