Every so often the photogrammetry in cities such as Chicago, New York, San Fran, etc. produce triangular objects, particularly buildings.  What is the cause of this?  Is it a bandwidth issue, settings issue on my pc and in the sim or my hardware?  I have been getting this a lot lately, particularly in cities where snow is present.  Thanks!

Bandwidth, but not necessarily your PC's bandwidth (connection). More likely overloaded servers at MS's end, or a slow connection somewhere along the way to said servers.

You may know this already, but for those that don't, your PC does not connect directly to the MS servers. It connects through many routers and switches. Any of those could be having a bad day.

So I guess what you are saying is even the most powerful PC in the world if money wasn't an option wouldn't fix that when it happens?  Any other alternatives?

Turn it off. 😉 I don't like photogrammetry at all. I loved the idea when I heard about it but 95% of it looks absolutely terrible. Odd shapes, bad colors... Awful. Besides, I like all my scenery to be of the same kind and quality so even if photogrammetry was better I might have turned it off for regular use. But imho the 'autogen' looks a lot better (from the distance I usually see it) so it's off here! I think it also performs better.

So true!

Having a rolling cache helps with this problem. When you turn the RC off, it has to draw everything as if it were the first time. Having it on, it just rebuilds what it has already downloaded. Try it out and see if it works better for you.

Fully agree!

If you have downloaded “melted” buildings they probably will look like that when loading them from the cache….

That's an interesting point. Does it mean better to leave PG off?

You will have to try it to see if it helps you : the same route with and without PG.

 

It also has to do with quality of PG data. I have consistent good buildings in San Fransisco, Gold Coast, Barcelona, Orlando, etc. Not by coincidence the PG cities that shipped upon release of MSFS. Since WU Great Britain, Asobo uses another source for PG and since then I feel that it has lost quality.

Bad connection. And as exposed above already, rolling cache won't help with it. Manual cache of the area of interest before starting the flight could.

It has to do with them rendering for the first time. Load in an area, let it get into the cache, exit the flight, and select the same flight again. The PG quality will be better.

Why would that be the case ?

Here I have a 600 mb Internet connection and I also see often melted buildings. 
It was with and without using the rolling cache / manual cache. So finally I disabled them.
I can imagine that pr tiles stored in the cache might help with a slower IN connection.

But if melted buildings are sent to your pc from the MS servers there is nothing you can do…

No disrespect, but you're off in your observation. I've got a 1Gb connection myself, and experienced melted buildings. I'll show some before and after pictures so you can see what I'm talking about. But, you need to load into the area you want to fly to get that region into the cache. Exit the flight, and then load back into that region again. The PG quality will be 100% better. Give me a few minutes and I'll show you what I mean.
