I´m on XBOX S.
Mainly flying PMDG 737 and inibuilds A320.
Sometimes in mid-flight LOD from high altitudes gets awful (very very blurry).
Did this workaround: Save flight (in PMDG also save “panel state” in the FMC), close the sim. Restart by loading the .flt-file: LOD was a lot better.
Think it is something with memory use.
