Huh. I actually only had to go down to 188%, but I dont understand that. Why would something disappear at a greater distance? That seems like the opposite of how it should work.
Some objects are designed to appear at certain distances,much like some are high detail objects. (Half the lovely details on Cardassian buildings don't show up at all on less than full display quality.)
Specifically, I think what's going on is that distance works kinda like echo location. Things are drawn not by theirproximity to YOU but based on their proximity to the outer rim you've set with draw distance.
By setting it at over 100%, you may be close to the object but high detail objects are further from your outer rim.
My suspecion is you'd see it from far away but it disappears as you get closer on high draw distances.
