Hi all,
I've found a reliable way to reproduce the missing/floating airport lights bug with Aerosoft Mega Airport Frankfurt in MSFS 2020, and I'm curious whether others see the same pattern.
What happens:
Arriving at EDDF from elsewhere: no runway edge/centerline lights, no PAPI, taxiway lights floating in the air or flickering. Day and night.
The pattern:
- Spawn at EDDF → all lights perfect
- Spawn at ETOU Wiesbaden (next door) and fly over → lights perfect
- Spawn at EDSB Karlsruhe (~100 km) and fly in → broken every time, after just ~10 minutes
So it looks like the lights only work if the airport is loaded at session start, and break when it streams in during flight.
Ruled out:
- Not memory (RAM 10.2/15.3 GB, VRAM 3.8/4.9 GB during the bug)
- Raising TLOD/OLOD to 100, Terrain Vector Data and Off-Screen Pre-Caching on Ultra, and switching to Clear Skies in-session changed nothing
- Default Asobo EDDF not installed
Setup: MSFS 2020 (MS Store), Fenix A320, Navigraph navdata, Ryzen 9 6900HX, RTX 3060 Laptop 6 GB, 16 GB RAM. Screenshots attached.
Questions:
1. Do you see the same "works on spawn, breaks when flying in" pattern, at EDDF or other airports?
2. Has anyone found a fix? I haven't tested yet without Navigraph – if you have, please share.
I've also opened a ticket with Aerosoft and will post any answer here.
