Well, I don’t want to blame them directly but as in KJFK, LFPG and any other big airports (Also can say that in cities containing more than 2 big airports) there is a performance issue. Eventhough, I’ve added LOD’s, reduced vertex count, etc… nothing seems to be improved. That’s where I have started to feel that “MAYBE, the problem is not caused by me”
We will see in further updates
