loaded from KLGA and KJFK v2 was not loaded yet. Is this because it's a demo or is this normal for this airport? We are now simming in 64bit. I thought this was a thing of the past.
This is obviously intentional, and surely not a bug. While in 32 bit, this was made to save you from BOTH an fps collapse AND an OOM, just because you will not risk OOMs anymore, doesn't mean your fps will not collapse, if we did the mistake of allowing to load KJFK when you are on KLGA, with the whole of the city in the background.
If anything, now that OOMs are not a problem anymore, we should be even more careful of fps than ever.
