I have all the LOD settings at max, with the lighting settings in the INI done to overhaul levels for the Wasteland Street Lights mod. I'm still getting object popping at a fair distance, and I seem to remember when I played last year that I didn't have this issue. No clue what caused it, but changed computers since then and did a reinstall, so maybe an INI tweak I missed?

In case it matters, my modlist.
