Thanks for your help. I had about 55 add-on airports, PMDG 738, FBW 320, Fenix 320, Pushback toolbar, is it cuz the problem? Add-ons too heavy?

Hi, of course these airplane mods are demanding, but whether these can cause these amount of commited memory usage, I donāt know. Would be may be a test flight worth with a ādefaultā airplane.
But as long as you not run into a crash because of low-memory-message and not set a high amount of pagefile ( as mentioned , with 64gig I have min 1024 and max 4092 ) I assume it should work. It is just all about āvirtualā memory and also windows itself set per default a too high pagefile (depend on kernel-image-setting itās min/max 9gig/depend-on-disc-space for 64GB RAM , the rules I mentioned sometimes in forum :))
For loosing fps in long time flight, exist a other big topic.
No, really thatās not a lot of items for community folder, and unless one or more of the mods has a memory leak that amount of mods wouldnāt call for that much ram usage.
1st thing to check, are all addons the latest versions?
Run with empty community folder and check ram.l usageā¦if its still high then the issue could be external such as windows installation, a virus/malware or bad memory.
Might want to check Event Viewer to see if there are any messages in there which point towards software or hardware issues
bad memory ??? that cause a crash, a bsod, etcā¦ but not a high count in commited memory 
I see the main mods which are known for hard system requirements, and may be one of these cause also that strange behavior. As mentioned, I would simple try the same 3h flight with a default airplane
Iāll try a long flight with a new empty Community folder, try If itās related with these mods. With adjusting VM setting now usage wouldnāt hit that high but around 50% once in a while, usually around 35%. Another thing I figured, would it be related with time acceleration? During a long flight yesterday, BBJ2 from VHHH - OMDB, I used the time acceleration 2X Direct cuz I had to go to work, I found that usage under time acceleration grew higher and faster than not using it.
Few days before I posted this topic, I remember I flew a Bell 407 under VR touring around New York for like almost 5 hours, when I removed my VR headset, I saw my monitoring APP warning me the usage went RED( which means over 80% of RAM ), Iāll try a new flight with default 320 without using VR. Adjusting VM settings in Windows works, but I found few system bugs after it, like clicking Reboot button the system will be super stutter, and losing icons and words in every windows and desktop, if I shut down the PC completely and restart the PC manually, everything back on track. Weird for me .
hmmā¦ that sounds like your system runs really in out-of-memory trouble. VR is also a good hint, who knows
Please also disable Windows Fast-Start ( extened energy settings, what should happen if click power button, disable fast-start ( ignore that ārecommended by MSā BS ). And dont forget to restart windows from time-to-time ( not only shutdown and start, choose windows restart in menu ).
PS. and time slew ā¦ I not trust these featureā¦ in many sims this feature is/was long time source of trouble. I would not wonder if same in MSFS. ( I remember also some topics, but not exactly what is was )
May I ask whatās your RAM usage while a 3 hours+ flight?
Since I had this issue Iām totally confused about it, canāt help but always checking mine, if it went through 50% then Iām worried. Right now Iām flying to ZWWW from UUEE with PMDG 738, after 2.5 hours the indicator shows around 29%(17.3GB committed, 10.7GB working set), sometimes up to 34% or 35% but always went down to around 29%,30%, I think this is a normal level of memory use.
Thanks for your help anyway.
thats totally fineā¦ may also the double values ( therefore I allways recommend to buy 64GIG RAM instead of 32GIG, of course if the budget for the pc exist )
In your screenshot we can also see, that your pagefile is seemingly at 9gig, where I set 1gig min.
Your non-paged pools size is a bit high and may be you should monitor that a bit ( can be an indiz for a driver mem leak , but also depends bit on connected devices etc. )
I need to search whether I found a screenshot of my last >=3hours flight. I normally fly the smaller airplanes and helicopers and that usually in the 2hours range ( very rare more , e.g. 6h so ).
In my usually 2h Iāam in similar memory range like your new values: (w/c) 10/25 GIG, some times till 20/30GIG
PS: what I can tell you, that DCS eats a lot more 
Should I set my pagefile to 1Gb? Will it make Non-Paged pools smaller? I see the dark blue bar is high, when I put my mouse on it, it saids: Memories occupied with inactive cache data and code.
I recommend to set your minimum value to 1GiG ā¦ the maximum I personally have set to 4Gig . If you unsure you can set the maximum to e.g. 9Gig or more. But I assume you should never see usually an increasment of the minimum value ( otherwise somethings needs to much RAM ).
The non-paged pool is independendā¦in this area lies parts which can never moved into the pagefile and if there is a memory leak here, it eats so your RAM till it is full. Usually these area is used by kernel drivers, etcā¦ An example was older network drivers, which caused so a real memory leak ( 10years and more ago , but some users still use outdated drivers (e.g. affected often the killer network cards) ).
The dark-blue bar is okay. In old DOS ages this was called āsmartdrvā ā¦ it is a windows cache ( files, data, etc ). It is a low prio memory and windows free that, in case apps requests memory.
There are tools like RAMMap , so you can manually clean that areas, but not recommended ( in special not, if MSFS is running ). see also: CTD (Resource Exhaustion Monitor) - #12 by MichaMMA
Thank you so much for answering!
Helped me a lot.
Iāll try to see if I could get a greater result.
Cheers.
