I almost hate to post for fear it will be a jinx, but rolling cache off has so far solved the problem for me. In the last 6 flights in different parts of the world, including my test flight where I would get the severe drops in fps repeatedly, I've not had a single instance of that symptom. I can't believe it's that simple and nobody else has mentioned this fix, but there ya go.

After turning off rolling cache I deleted the cache file. Last test I'm going to try is rolling cache back on which will be with a fresh cache file - will tell me whether turning off rolling cache, or a fresh file fixed it...will report back tomorrow night.

I always delete the rolling cache after an update.  I Did and re-made it after the  update and I get the 30 secs to one minute drops.   I will delete it again and turn it off and report back after a flight.  I will try anything at this stage.

Simon,

I guess that answers my question whether it was a stale file, or rather simply the fact of rolling cache being enabled. Sounds like it's a rolling cache functional problem, which according to others has been introduced with World Update 3.

Thanks for the update Simon!

I will delete the rolling cache and fly without it and see fit the problem persists and report back.  Silly to have to go through this (1 min periods of 10-15 fps) when you spend alot of time sorting out your hardware and settings to get an issue like this pop up on landing or climb out 😁

I always fly Rolling Cache OFF because it affects performance a bit but still having this issue. Flying Rolling Cache ON doesn't change a thing. MSFS is flyable only after turning Online Functionality OFF. I do hope something is done for this in Sim Update 3.

I have both manual and rolling cache turned off, and I still have this problem.  The only thing that fixes it for me is turning Online Functionality off.

-EGLC on the ground in the Carenado Mooney right as the flight loaded with a custom weather preset similar to fair weather.

I had this after taking off from EGLC too.  After a couple of minutes I get the 'manipulator' message and it hangs for 20-30 seconds before continuing with low frame rates of about 15-20 FPS. 

 

I thought it might be the photogrammetry but still the same without that on.

I have a feeling you are correct; this is pretty unexpectable when people have their systems under control and stable and are being screwed by some sort of MS server issue on a daily flight basis?

So I've been getting big frame drops since the last update. After reading about the rolling cache possibility I figured I'd give it a go. So I just tried a quick flight in central Itay, random location with rolling cache disabled and flying with real world traffic but no multiplayer.

Ultra @4k 37-40fps with sudden drops to 1fps - also noted 11fps in main menu before the flight.

Now I have read that some people seem to be pointing the finger at the new ship traffic - I'm running it but I'm pretty sure I had this issue before I updated a couple of days a go.

I'm not running the ship traffic addon.

The ONLY performance problem solved for me by turning off rolling cache is the instances of severe drop in fps that usually last a minute or two, then returns to normal (30-35fps drops to 10-15fps with low gpu and cpu utilization). Turning off Online Functionality also fixes this, but for me is only needed if I have rolling cache turned on.

For those that have rolling cache off but still have the problem, are any of you using manual cache?

So can anyone report if there is any improvement considering there was an update released today?

I can't  yet as I am still downloading, but they did mention various stability fixes in the patch notes I believe.  We can only hope!

just had 3fps in menus, trying a re-launch now.

 

this is folly

after last update this problem is still here...😰

Unfortunately, the problem still persists for me after the update too.
