Lost performance after SU9 update.

What did you have in the Community folder ? Landmarks, airports, ac (AIG) , cities, mods ?

Myself I have POIs like well known churches, hotels, tv towers, well known buildings, all based on Google and DL from flightsim.to.

Perhaps with SU9 MSFS has an issue with those objects….

Yep I had the same - stuff from flightsim.to. Airport updates, We Love VFR, Chairlifts etc.

Must be something weird happening with one or some of these in SU9 as removing it all completely fixed the stutters.

Hmm I might try disabling we love vfr too then. This is interesting, I also noticed running air manager increases the frame drops.

I was getting 25-30 fps with massive stutters at KATL no AIG traffic night time with no clouds.  I deleted the 7 addon Photogrametry Sceneries in Content manager..  same scenario...44-47FPS... no kidding.  offensive initials not allowed mate?  Although I fly a lot in Germany, Iberia, and Japan so hopefully this gets fixed.

This seems like a pretty typical gain. Really glad it's helped you. You can always quickly reinstall the photo cities for Japan or elsewhere and then fly. After the flight, uninstall and the next time you restart the Sim, you'll be g2g!

Why would PG since SU9 have a negative influence on framerate compared to the other SU ?

Today I will do testing so all info I have read and you guys might still have is welcome

I think this issue got dumped into the SU9 thread when there was no connnection intended, as people are saying this PG issue has been apparent, for some, since Dec 21.  Wht I can say now is removing all PG cities from the 7 WU's did not change CPU load at EDDF, which I chose because it's pretty hard on CPU.  Others are saying doing this helped w/ US and CA CPU load, or something like that.  I'll give this one more try today as well--uninstalling all 3D PG cities, and seeing how performance in to KORD is today and that is a fair test.  I say 'in to' because arrival is always harder on the main thread as I outlined in the link above.  If this test fails as well I have to think it's, as far as my install and set up goes, another one of those discoveries that turns into nothing, hence my jadedness in this thread!

Does this happen at all complex airports in the US, or just KATL?  Perhaps this dramatic difference is unique to certain airports?

Click on your profile avatar - upper right in sim.  It will give you the option to select servers.  

The servers in that list are for multiplayer - they are not (necessarily) the source of the streaming scenery. MSFS establishes anywhere from 5 to 12 discrete TCP/IP connections when it is running, to different servers in different geographic locations.

Running lookups on the IP addresses in past sessions I have found some are Microsoft Azure, several go to Akamai, and there is always one connection to an Amazon AWS server - and that one typically has the highest or second highest continuous data flow for incoming packets.

Geolocating IP addresses is not an exact science, but checking the various server locations MSFS is connected to while running (the last time I did a network analysis) showed the Azure servers were is Seattle and Portland, the Akamai servers were on the east coast, (in NYC and New Jersey), and the Amazon AWS in Illinois. The “server” showing in the MSFS UI was “US East”.

I noticed it at KLAX after a flight.

seemed to be we love vfr for me.

I did my final test for this at KORD a few minutes ago.  There is absolutely no difference between having all PG cities installed, or uninstalled (and closing/relaunching MSFS).  So for me this is yet another magical solution to a problem that doesn't exist which of course is what is seemed like it would turn out to be.  Apparently for some others it appears useful, operative word, appears...

Do you have the latest version? this mod was updated a couple of days ago.

Ahhh no, I’ll see if that makes it any better. But to be honest, I personally just think SU9 is a mess.

Give it up Noel. You shot from the hip rather than researching and understanding the PG workaround, failed to comprehend what it was or where it applied and made yourself look like a fool. Now rather than admitting it and moving on, you're doubling down and insisting it's bogus and thereby undermining simmers who could actually benefit from this proven workaround.

I did some testing all around the world and it is not dependent on location. I tried Asobo EGLL ,Asobo KATL, FlyTampa YSSY, Asobo RJTT and MK Studios LPPT.  Photogrammetry area or not doesn't matter either. It also does not matter if you disable 1 of those 7 PG sceneries or all 7 the result is the same.  I was thinking maybe If you disable Photogrammetry and then restart, come back in and go to the same location it wouldn't be affected.  But it seems as if no matter what I do, if even one of those 7 PG sceneries is active the frame rate tanks no matter where you are in the world.

Next I tried getting rid of everything in the community folder and letting it rebuild a new CFG. At first I thought this was the key. As soon as I installed those 7 PG sceneries every thing seemed good.  So then I decided to restart the sim and lo and be hold the FPS loss was there again with a new CFG and nothing in the community folder.  I am beginning to think that some installs have gotten corrupted over 9 updates and the whole thing just needs to be reinstalled.  It seems that it is a large number. There already several threads but this on has 64 votes in 2 days... So it's looking like Asobo did something.

Very odd bug.

I'm also miffed that the stupid TAA ghosting still is not fixed.  

But the good news is once I disable those Photogrammetry sceneries messing with everything. I'm gettin' 30FPS with no stutters on high/ultra, TLOD 400, RS 100 at 2560X1080. So after 3 hours installation I'm back to where I was minus some photogrammetry. Also, the clouds look really good now, so there is that.

EDIT: it does only affect the frame rate in the US on the ground.... wierd.

Thanks Jim.  Something I did not know. 

I think you may have caught on to the reason I was for asking his server location as I was spitballing that some of the issues people have been experiencing with the PG cities being installed is that the geolocation of their IP address maybe influencing whether or not those assets are being loaded into the sim and affecting performance -  despite them actually flying in a different part of the world. 

FSX/P3D had a nasty flaw where certain content files are loaded into the sim even though you are no where close to where they would actually appear in the sim, needlessly using memory and chewing cpu cycles.  That was part the impetus behind using the Orbx region changer and not having a region active that you weren't using (the other reason being is it allowed the developer to customize scenery for that locale within the limitations of the scenery landclass tables).  

But the streaming of these PG scenery assets is a different ballgame and I don't think one could detect locally if the content being push to the sim is just for where you are flying, without other unnecessary stuff "clogging the bandwidth" and potentially affecting performance/memory etc. 

I use to use Procmon to determine what was actually loading into the other sims for performance queries and have used it with MSFS, but not sure if it would log the individual PG assets or not?  Maybe I'll try it.

FWIW, to the others having issues, I can just verify that I have had and still do have excellent performance on my lowly 4790K/1080 ......BUT - I have never installed any of the world updates and PG cities outside of the US - so that helps possibly explain why this affects only certain people.  I have noticed a slight degradation in SU9 with the CPU being hit harder and my solution was to raise render to scale from 120 up to 140 to push more to the GPU.  I run 1080 resolution. 

I hope everybody gets it sorted out soon.

Nothing to give up.  I never said it was bogus here's what I said:  So for me this is yet another magical solution to a problem that doesn't exist which of course is what is seemed like it would turn out to be.   Picking up substantial performance and the claim is huge, from less than 1 mb worth of files seemed to me likely to be bogus.  After shooting from the hip and learning otherwise, and finally getting around to understanding what was being said I think I did valid tests, it failed completely, there was no difference whatsoever, just reporting my experience with this issue.  I look forward to learning what it is that is causing such a dramatic deterioration in performance for some, and yet for others absolutely nothing.
