I had the sim runng with TAA - gives me generally a better overall gfx experience.
Now: when I switch to DLAA or DLSS, these trippy lights dissapear. Reproduceable with nvidia drivers 566.14 and 566.36. I’ve updated my bug file accordingly…
See: Strange blinking lights at every airport, a/c independent, TAA only
Unfortunately I cannot determine wether this strange behaviour is nvidia- or Asobo-related…I’ll leave the bug report and mark THIS post as a (temporary) solution.
