Triangular Buildings / Photogrammetry

Higher resolution files (higher LODs) are different files that cover a different area. 

How do you know that? Is there any documentation about it?

AFAIK rolling cache is a single big file.

But with a lot of seperate and different files in it, I presume.

just curious:  Do you ever see triangular buildings in the distance?

Sure but when approaching those buildings they take their correct form.

But that I see this is probably due to using one wide front view consisting of 2x 43” 4K displays with a zoom of 0.35.  This is comparable with 1x 43” display using a zoom of 0.70 or a 32” display using a zoom of 0.95.

OK, but this is the limitation of relying on only downloaded data.

The sim will only seek to download a radius around your plane and it won't seek the highest LODs for distant objects and that's why you see triangular buildings.  I have a much slower internet connection than you do (25MB/s) but I use the rolling cache and once I fly in an area like Orlando or Tampa or San Francisco and the higher resolution data gets into the cache, then I no longer have triangular buildings.  I will still have triangles and flat buildings in areas I've never visited and there are cities which suffer from poorer PG like Paris sadly.  It has melted buildings but it's still better than nothing imo.

You are correct that PC operations are faster if you dont try and cache downloaded data and if you don't mind triangles on the horizon or other possible glitches due to slow data downloads that may occur then by all means don't use the cache.  But I think its serves an important purpose and it does it well for people like me.

I'm not sure where to point you to at the moment but lets start with these.
