Already we have another thread about this but today I will do several take off / 30min sightseeing / landing tests and post the results here.

Yesterday I did a sightseeing tour over the Netherlands: EHAM - Amsterdam - Rotterdam - Maasvlakte - The Hague - EHAM. 
Speed 250 / Alt 5000 ft.

Just after landing my framerate had collapsed :

 

Today I did 4 things before making the first TestFlight :

1 LOD terrain + LOD objects : 200 to 180

2 Disabled PG cities : Australia + Japan + Goty (I fly in EU + Northern Africa)

3 Disabled all flightsim.to Addons (poi’s)

4 Disabled AIG ac (PSXT + RT + AIG)

 

The first TestFlight went well and I did not see a framerate drop on both pc’s. The screenshots are from my server (2x 4K).

 

 

 

 

Second test : AIG only enabled. After landing.

It starts to look that I have to look into the flightsim.to Addons I had Enabled.

I have a Netherlands base : bridges , stadiums , Oosterscheldekering

NL VFR : many known buildings  + extra known bridges 

NL IFR : extra known bridges 

I will have to test them. All of them are Google objects modified for MSFS and made 1-1,5 years ago…

Also I have to add that I am testing at daytime while yesterday I made the flight at 20.00h. So a low sun and lots of shadows.

AIG doesn't seem to have any influence on FPS or stutters here, so I guess that one of your mods (or all?) might be the cause of your drop in performance (apart from the numbers 1 and 2 in your above mentioned list). Will you do a test run with only your number 1,2 and 3 disabled in your list and see what happens?

Our posts crossed, my apologies about having probably caused any confusion.

Don’t worry . All suggestions are welcome 🙏🏼 

Awesome analysis. Maybe one test only PG enabled and another test only flightsim mods. Pretty sure there is a mod there missing with the FPS

Third test : enabled all my addon scenery/mods again. No drop in framerate….

 

The only thing different with yesterday is that I have PG cities of Japan, Australia and Goty Uninstalled and both LOD terrain + LOD objects at 180 (was 200)….

I am going to make a full flight now from Ajaccio Corse to Amsterdam Schiphol to test a longer flight….

I disabled PG in the options and removed welovevfr and that is what fixed it for me. Oh I also lowered TLOD to 150. Objects is still at 200. 

Guys, this has already been told to Asobo. It was Also mentioned in the SU 9beta forum. Asobo has not yet replied on this. So yep, maybe again just report this on there forums. But for me it also helped.

Ten minutes into a flight from EHAM to EGCC in the FBW my FPS suddenly tanked. I reloaded the sim and tried the same flight again and it was fine. Very odd. Could it be that this is some random bug that kicks in now and again and that uninstalling photogrammetry cites or whatever just appears to cure it whereas it's just that once the sim has been restarted it doesn't occur again? IE Placebo.

Reason: Asobo continues to have basically no clue about their own engine and simply plays around with it. Sometimes they get stuff fixed by chance, sometimes they break things. If they would really KNOW their own engine, such things should not happen 2 years after release... /sarcasm off.

TLOD should not be > 150 IMO.  No problem with We luv VFR region 1.

The PG cities bug/fix only impacts your frame rates when your aircraft is ON THE GROUND at an airport in an area with PG baked into the Bing scenery data. If you saw frame rates dive during a flight, it's something else.

Halfway in my flight . Just crossed the Alps.

Unfortunately no clouds to be seen as they would have taxed the system more.

In my vids I manually added clouds ….

Amsterdam is a PG city and I have the BeNeLux PG cities Enabled.

But Japan/Australia/GOTY PG cities have been Uninstalled.

If this flight turns out good I will Install Goty PG cities again as Utrecht is one of the PG cities in that package.
