His image is showing entire system memory usage because he is on the Performance tab.  A better depiction of how much memory MSFS itself is consuming is to use the Processes tab and then click the Memory column to sort descending as shown here.  Don't be fooled by my low memory usage in MSFS as I was only on the main page.

I'm using Afterburner which is looking at total memory usage not just MSFS.

KLAX with Fenix A320... 50% AIG and nearby airport sceneries... 52~60 FPS and smooth...

And there ya go.  MSFS is using 16.6GB of memory.  The other 20.4GB is being used by other apps.

Yep there you go.  Clearly no need for 64Gb for my usage unless 2024 doubles what's in use now.

If other apps have priority over MSFS then you get performance issues... in my case, it was noticeable when panning using the eyetracker and now I don't get those anymore... I think the sweet spot is 48GB... If the plan is to have MSFS with a few planes and stock scenery then 32GB is fine...

Maybe this screenshot is better at showing the resources used...

Which means with his setup with those files running her would be exceeding 32gigs.   Inevitably there would be paging and system performance would deprecate.  With 64 he avoids that.  I just checked and I am at 32.3/64 used with just my normal MSFS setup and supporting apps. PMDG777 at DDKEWR.   ASFS, SPAD, Aviasoft, CLS2Sim, OI4FS, AIGTC  and simshaker.   Nothing else running on the machine and MSFS is at 16.3GB the other 16 is ancillary apps but that means I would be at 100% of my available memory with 32.  So even with MSFS2020 on my setup 64 has allowed my system to use 32 which would have been 100% of my available RAM.  

And I don't have any popping objects when I pan quickly anymore even at DDKEWR.

Yup, I believe Asobo knows this and that is the reason for the "Ideal" specification.  If one doesn't run a lot of supporting apps alongside MSFS they will be just fine with 32GB.

My MSFS always ran fine with 32GB although it took lossless to improve FPS which is irrelevant of RAM however it still led to stutters and sometimes momentary pauses while objects loaded especially with view changes or quick panning. 

After moving to 64GB I just departed DD KEWR in the PMDG 777 with AIGTC at 75% so 250 planes around me and for the first time ever, ZERO stutters, no pauses, every single rooftop light in NYC was illuminated red, no lights or scenery tiles popping in and out in the distance, LOD was pinned as far as I could see I mean it was almost surreal.  So yes, MSFS2020 and I am sure 2024 will run fine with 32GB as they always have however this morning my "total" RAM consumption was 38GB with MSFS using 19.8 and my MSFS add-on only, nothing else running consumed the other 19.  HOWEVER and this is key, if I only had 32GB MSFS would not even get the full 19 it never went above 14-15 on my machine to make room for other apps.  This is almost unlimited headroom and MSFS can maximize all the RAM it wants...  

It's interesting to see and I am actually surprised.  I didn't think there would actually be any benefit at all especially with MSFS 2020.

So it seems MSFS2020 will use more RAM if it’s available. Similar to VRAM I guess. This is interesting!

Ive seen some page file usage on the last couple of flights (lots of addons including ATC, AI traffic etc).

What a weird recommendation.  I only use PMDG/FBW/AS and WT 787X and at pay ware KLAX a lousy 14.8Gb of total RAM in use by all applications including FSLTL, APL, SLC, GSX and an open browser running Simbrief on one page an Youtube on another.

I'm pulling 28-31gb now since going to 64gb.  I've noticed less audio hiccups/static like noise also when various tasks used to cause resource spikes.

And what was total RAM in use system wide when you had 32Gb installed?

No idea. But now slightly smoother. Not terribly expensive. Not looking back. Will hold me for the next couple years until I rebuild

Maybe, the more you have, the more Windows will allocate for MSFS to use? 

In other words, maybe the amount of RAM that MSFS can use is influenced by how much the OS is "willing" to make available - which might, in turn, be influenced by how much RAM overall is available?
