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? 

This certainly has been suggested by several people here over the years and with VRAM as well.  Of course, my question is when the system is using less than 50% of the 32Gb available RAM I can't see any reason why doubling physical ram could have ANY influence on that.  Only someone who has tested for this can say.

My experience is better with 64. 64 has also been set as the ideal spec for 2024. That’s good enough for me in terms of a cost of less than 200

Yes, and it's been stated if you're running huge RAM demanding apps alongside then this might come into play.   I'm always very puzzled when anyone makes claims about 'better' when there are a zillion factors affecting each and every flight.  But, I understand you believe you can attribute a better experience when you doubled RAM.   Could be you have far more demand than most, are maybe running 4K in two screens, so maybe you were closer to maxing out your 32Gb than the typically less than 16Gb in use in my system.

My experience was MSFS never used more than 14-15 with 32GB and total system consumption was never above 24. 

Now with 64 MSFS is up to almost 20 and the system is up to over 38.  It does appear the system will use more if it is available.  

Just my personal experience thus far and similar to @micstatic it is more fluid, no stutters, no pops, it definitely seems to be running "better" although my system was running very well before so I am actually quite surprised by the results...  

Besides the positive anecdotal experiences, the video I posted a few pages back seem to confirm it;

 

Just this week I upgraded from 32gb to 64gb. I hadn't yet seen this forum / the MSFS 2024 system recommendations. But same 2 sticks, same 6000mhz, CAS Latency of 36, just doubled total GB available. I'm definitely noticing that there are less (near 0) stutters in intense areas. I.e. I used to always get stutters when panning or turning on the taxiways at KORD, in the NY Metro area. 

I'm not suggesting you upgrade too and that it'll resolve all your issues - I had my system pretty fine tuned visually/graphically & settings wise to my taste. No AI traffic. It's just the situations on the fringe where I used to expect stutters... they are no longer there or very minimal and I'm kinda surprised

Those who have upgraded to 64 from 32 and see huge improvements remind me of audiophiles comparing expensive speaker cables, we've had this discussion before, but I could be wrong, I'll will upgrade if I have to, but not before 😉

No one is actually claiming huge improvements.  Most of us are suggesting incremental improvements we weren't expecting adding to overall RAM consumption and MSFS RAM consumption and noticed less micros pauses, popping objects or audio and can see our RAM consumption has gone up since swapping. 

No one is here claiming it magically increased performance, no one has even mentioned FPS, it's been a pretty balanced conversation.  

And BTW, if you are an audiophile then cables do matter to an extent but more on the gauge so a good 14 gauge should be the same as another good 14 gauge but a 24 gauge connected to a sound system worth thousands is the weakest link at that point.  But yes, some people can tell the difference the same way after years of driving a race car I know when the tires are a 1/2 PSI off.   A full PSI changes the whole contact patch of the tire.  So yes, there are people that get things to "that extent"

I can understand someone buying a 4TB drive in anticipation. But it is hard for me to assume that I am going to gain much of a benefit in having 64 instead of 32 GB RAM. Anyway, I can do that later if it seems warranted.

It all adds up though. Like I’ve mentioned earlier, I’ll do a CapFrameX performance comparison (which “measure” stutters objectively), IF I end up upgrading to 64. Which I might do sooner rather than later based on positive feedback in this thread.

Ive done similar performance comparisons with EXPO on + SMT off (+11% FPS) and before/after upgrading to Win11 24H2 (+4% FPS). 

But yeah, there’s definitely more to performance than increase in FPS ie an increase in overall smoothness.

So I was getting very smooth performance with 64 GB RAM on Windows 11 23H2. However, after updating to 24H2, I am seeing the same stutters I had back when I had 32 GB RAM.

Anyone else experience this?

Turns out this was due to the Nvidia 565.90 driver. I rolled back to 23H2 and still had stutters. Then I rolled back to the previous driver, and had smooth performance again (with 64 GB RAM.) For some reason, driver 565.90 doesn't play well with my system. 

Also, it's amusing how many people are ignoring actual video evidence + a lot of anecdotal evidence from several users. 64 GB definitely helps in MSFS 2020, even if the sim uses half of your available RAM. For some reason, the sim goes to the page file even in such conditions, which causes massive hitches. With 64 GB, that is not a problem.

It remains to be seen if it has any benefits in MSFS 2024.

This is exactly what I was thinking.  Because there is more available ram, more is allocated which allows for more of the resources being downloaded to go straight to ram versus the page file.  If those resources are instead on the page file, a hitch occurs when they are paged into ram.  Just a guess on my part though.

That is exactly what it does, stick in 128gb and see what happens!

Like fooling wine tasters by sticking a fancy label on a bottle of plonk.

At least RAM performance/usage can be analysed a bit more scientifically 🙂

And it has been, a video has been posted with actual data yet people seem to ignore every piece of evidence posted to repeat the same line of it being some placebo thing. It's starting to become a bit intellectually disingenuous in the debate.
