Display Settings Change Spawn Room Objects

GeForce Experience recently changed the recommended display settings in Overwatch for my video card without explanation, and I’m trying to find the ones I used to have since I don’t need more than 60-70 FPS (my monitor caps at 60). I thought I found them, but… I’ve noticed a lot fewer objects to knock off the shelves/racks (ammo cases, oxygen tanks, etc.) in the dropship spawn rooms, and someone in game told me that it’s controlled by the display settings.

Which setting controls how many objects show up on those shelves and in those racks, and what’s the minimum value to have them fully populated?
