I think this point is a bit of a distraction.
MSFS 2024 has recommended system Memory specifications as 32GB of RAM and ideal 64GB.
as you can see it here:
My system has 32GB and while monitoring the RAM load it never goes dangerously to 32GB in most of my flying sessions.
If one flies in New York for example with a lot of mods and photogrammetry one can expect some shaffling but in a… Romanian country side I wouldn’t expect such problems.
Why my example matters?
Because Romania is in East Europe it doesn’t have any sim update over it so no special features there other that rather good terrain elevation data and aerial textures. So if I fly around a spot without any objects usually nothing happens, it’s a breeze for the sim, but if I create a scenery in DevMode and add some base MSFS objects and fly around the scene again I have pause of obvious reloading of the scene.
It’s a small airfield, some objects placed there nothing crazy all MSFS base. If I fly a bit away (but still in visual distance… say 2 miles maybe less the scene objects are unloaded… sometimes they are hidden by some forest or hill… when I pop out and they need to be draw again… the system hicks up because… “oops… we thought you went away chef”. This is an unwanted behavior. There is nothing around to require more space so no “anticipation” excuse either. Just aggressive and overzealous memory cleaning.
And before someone comes with the funny “turn off antialiasing if it doesn’t look nice enough for you” type of comment 
I have 10Gbs internet optical fibre and play from France. So no, it’s not the internet nor the wifi as I play with PC wired and wireless VR and the headset doesn’t have any issues.
