Objects quality is the most "laggy" option in the game and even on high end machines setting it beyond low/normal will kill the 60 fps target, but setting it to low also makes the items (loot) like food and weapons disappear from a shorter distance so I really think that Objects quality and Items fade/render distance should be separated (they should not be tied together) for a better control of the game graphics because items are way more important than good looking trees.
Maybe in the future items could be rendered at a way longer distance without being that laggy, that way we could look for loot with a sniper scope or with binoculars for example.
That's my dream.
