Ill open up a new thread because I did some testing and found some connections. My Sim has severe microstutters in any scenario displaying heavy clouds. It doesnt matter if those are created by live weather or by a preset. For demonstration I used the storm preset and the stutters are clearly visible in the sims FPS monitor:

The stutter occurs every 3 seconds with the same time interval in between. The time period is roughly equal to the performance graphs distance in the FPS view e.g. next freeze happens when the purple line hits the end. The sim "hangs" and then "snaps free" like 2 seconds later.
I am running a 5600x, ASUS 4060ti 16GB and 32GB of RAM. Usually my sim is very well balanced and able to produce decent FPS almost constantly. This problem definitely wasnt there a few weeks ago and I cant really determine when it started.

Anyone else?

Your manipulators are high, try to disable 3rd party addons and see if improves the situation....If you say it's the clouds than you can also try and reduce cloud settings and see how it goes.

I'm also experiencing stutters more than what I was used to, in either default weather or with an external weather injector...

It got a bit better with one of the last updates though.

 

Since the server issues that started last week I have had some potentially serious problems with MSFS.  A lot more random stutters and I am now getting severe memory leakage issues.  First the sound goes by randomly cutting out and after that 5 to 10 minutes later MSFS starts locking up.  At first very long 20 second pauses and after a few other long pauses it gives up the ghost completely.    

Before the server issues not an issue at all except for maybe the random half second stutter a few times during a session.  I suspect M$ is still having server issues!

Its not exclusively clouds but also complex planes or high density sceneries causing that. Even though my FPS remain acceptable in those conditions. The stutters also wont go away anymore when there is less clutter in the sim later. Only way to get rid of it is to restart MSFS. Seems definitely like a memory leak to me.

I also fail to install the latest W11 update from June 11th due to downloads being interrupted. I dont know if this is related....

solved. P42s SimFX was the issue. Dont buy that unless its updated or you have an i11 510000k CPU or something. Stutters are gone as soon as I deactivated this addon.

The SimFX addon causes a major fps hit. Here are my tests:

Without it: max fps in cruise level = 50 fps smooth.
With it: max fps in cruise level = 41 fps with constant drops to 30!

Now the question is answered why these effects are not available by default. 😉

I'm sure that by far the easiest and soonest attainable solution to the eternal problem is to sync our blinking with the stutters!

So there was never a memory leak...  

At what point did you see your free memory depleting and not releasing to lead you to believe it was a memory leak?  

I can't count the amount of people who see an issue and jump to "memory leak"  

I had really bad stuttering and drops from my stable native rate of 45fps down into the 20's for about 72h at which point I remembered I had enabled PG and created a rolling cache.  When I disabled PG and the RC all returned fully to normal.  I've had several normal flights since then, and decided to turn PG and RC back on and all's well halfway thru this flight, FWIW.

Hmm i guess all those "effects" come at some cost. I had the same issue. A couple months ago i think last year AIG introduced effects on their AI aircraft. While a few of those effects are ok some of them definitely cost a few frames .. which i would rather not part with. Had to delete them . ( I can do without APU exhaust and engine heat blur effects on AI aircraft). If someone from AIG sees this it would be nice to have the option to add or remove these effects as needed within the GUI. (I ended up deleting the worst offending effects files to get my 3-5 fps back). Sounds like those packaged effects recently released for sale is having a similar impact.

For me decent frame rates and low frame times are too precious to part with for this kind of stuff. But then again i can only speak for myself i am sure some others will find the value in having them loaded and is prepared to take the hit on frame rates.

The funny thing is for me if there were no performance impact having all of these effects really only makes sense on AI as I never see the outside of my own sim plane other than when it is at the sim gate.  

I mean can you even go outside the sim plane in sim flight without sim dying in the process???  There is no oxygen out there LOL  🤣🤔😏

@Noel: Do you use Simfx and Immersion Packages?

@soulflight:Sorry to be late to the party, did you do anything about it? Besides disabling simfx? Out of my perspective it's not a performance problem, it's somehow a polling problem 🤷🏻‍♂️, I opened a ticket today with P42, and wrote:

Good day P42 team, I must say I love Simfx and have both immersion packages, 777 and 320. Out of my perspective it started when I added the 777 immersion package. I got into my new pmdg 777, immediately I got a polling stutter, or let's call it microfreeze. It's every 2-3 seconds and the sim freezes for 1 second. If you reload the flight, you can not get rid of it. If you restart the sim it can get rid of it, but reappears later in the flight again. I did not find a way to trigger the behavior, so I can't reproduce reliable. But I can reproduce, that if I remove Simfx it's never happening. To be more precise it happens in the pmdg 777, the fenix a320, the tfdi MD11, those are the planes I fly at the moment exclusively.

I also found a AVSIM thread which described the exact same behavior.

I really hope we find a solution to the problem. Kind regards McDaniel
