obviously,

but did you ever check your actual MFS performance?

32 Gb RAM here.
All my settings are on Ultra, except the blur effect which I don't like, LOD @300, and I am using a 4K monitor.

The GPU runs at 100%, which is fine, and the CPU generally gently sleeps around 16-20% usage.
But I have NEVER seen the RAM going above 45-50%, never.
Even with the FBW A320n, heavy weather + complex scenery.
So 64 gigs for me would be a pure waste of money as long as I don't use VR.

yup, when I went from 16gb to 32gb MSFS started using more. And no difference in performance.

That's what I'm trying to explain but they don't understand anything.Thank you for confirmation.

When I increased to 32gb, I saw a significant decrease in stuttering and no more CTDs in areas where it was regularly crashing out. The sim has run great for me ever since, and only one CTD.

I have to agree with this from my point of view...

I am on 32Gb RAM.  All settings on Ultra (No Blur, No Sunrays or whatever they are called)  except I have LOD@200 and use a 2k monitor rather than 4k.  My GPU runs at  67%  my CPU runs at around 10% and my ram utilisation never goes above 46%, unless I am in heavy overcast and raining which bumps all the figures up a couple of points.

Again I don't use VR but I do have my system set up to lock at 30FPS using the   Radeon Software.. not the ingame settings.  I also have all rolling and manual caches off..

So Likewise..  I can see no need to go to 64Gb at this time.

After the beta I upgrade to 64 gb and since happy 🙂

André, always nice to see you around my friend!

Great to see you David, hope you enjoy the new virtual skies 😉 and maybe remind you at those beautiful skies you have seen a lot in real life 🙂

the simple trick is to see Page File Usage,

if it is more than 0% - you are using SSD or HDD for memory requirements (which is relatively slow)...

But isn't the real issue WHEN is the paging happening?  IOW, if paging happens in a place in runtime that does not impact stuttering, for example as a pre-fetch operation of sorts, it's just another of a zillion background processing that is always happening.  I remember when I had a 5400rpm HDD and used a RAM-drive to help reducing paging and even then--nada, zip, difference in anything meaningful.  Right now I have 2 NVMe m.2 drives and have to think those are so vastly superior to the old HDD or even the SATA3 SSD that it not going to make a bit of difference except, of course, you can show paging isn't happening w/ 64Gb.  My sense:  much ado about nothing meaningful.

as I said in my post "no difference in performance"

i have 2 systems , the one with 9900k @5.2ghz 2080ti with 32gb no problem ,

the gpu is to weak cant run the same settings in 4k.

sytem 2 5950x and 2200mhz 3090 , it use up to 28gb ram and up to 19gb vram 

uppgrade to 64gb to be safe , it not hurt anything wy not 

i see no benfit at all with 64gb on mid end sytem with a 2080 or weaker gpu

and up to you to decide , if i remember right the old rule of tumb , min ram 2 x vram

lot here run 4 x vram on there systems were they probaly be ok with 16gb

Can anyone here show any evidence of how or even why paging induces stutters in a modern system?  I still have a hard time believing in a multithreaded app w/ an 8core or better CPU, paging is going to interupt anything in runtime for MSFS or P3D.  It's absolutely not good enough to claim it's smoother because a million factors go into the total flight experience.

What I would really like to learn is exactly how MSFS uses VRAM and SYSTEM RAM in terms of work flow.  This matters hugely in this discussion as it's entirely plausible MSFS looks ahead far enough in terms of what potentially will be rendered next to insure something like paging to disk and reading from that disk never interferes w/ the immediate rendering task at hand.
