FS2020 multi CPU support , max core count and max memory support

Hi
So I have been wondering what the FS2020 engine actually does support from a CPU point of view. So looked around and have not been able to find any information about this so I hope someone can help answering these questions.
1: Does FS2020 support multiple CPU’s - not to be confused with multiple cores. Say a Xeon workstation with 2 CPU’s or more.
2: What is the maximum number of cores that FS2020 can make use of? With todays 24/48 core/threads and higher CPU’s it is a relevant question.
3: The same question goes for memory. I currently have a “small” setup with 32 Gb but also have acces to a dual Xeon with 256 Gb memory - it can even be expanded to 512 Gb - so how much can FS2020 see and effectively work with?
Hope someone from the dev team can answer…
Thanks for creating something that my wife already hate and I have only just started.

PS if anyone should also happen to know if there are plans for support for real sim home builders and if so what companies are they currently working with…

It is very rare for games to support anything than standard consumer Intel and AMD processors, even though there are special processors with 24/48 cores and Dual Xeon processor setups like in Workstations and Servers. Don’t hold your breath for MSFS or any other game to support such hardware.

I’m not a dev but I personally would expect the sim to work on such machines but I’d not necessarily expect improvements in performance. Especially not if workload is split over CPUs and ECC-RAM is in place.

Really depends on the machine you’re comparing it to. My assumption is that it works better on a single 8 core than on two 4-cores and also better on 32 GB non-ECC than on 64 GB ECC.

However, from what I’ve read on the internet, you won’t have much advantage of a CPU beyond 8 cores, except when you’re planning on running several other stuff in the background.

Also, the sim seems to take advantage of high single-thread performance. Which is not really the USP of Xeons.

Finally it’s doubtful that the devs have optimized, tested or even planned the software to run in multi-CPU environments for obvious reasons.

Of course the thing might partly change when DX12 comes onto the table.

Well I would disagree on the memory. FS2020 is all about huge amounts of data but you need to be able to access it which is limited on “regular” chipset’s. According to a test that Tomshardware did this is what they found:
“64GB didn’t help, incidentally, as populating our test PCs with two DIMMs per channel results in lower overall memory performance. This is expected, though if you have an X99, X299, X399, or TRX40 platform using quad-channel memory is a different story.”

But I guess I will have to find the time and create the system and test for myself. Will most likely not be before after the holidays are over.
But I would still love a reply from someone from the development team.

Whatever happened with this, have you learned anything since this post?

Sorry - never got a reply from Asobo. However looking at “performance monitors” that looks at the individual thread usage it seems like FS2020 is pretty much a single core app. Yes, there may be some other cores doing something but the main app is not great at distributing the load over multiple cores.
Now, I am sure Asobo will state that is NOT correct but I don’t see it being spread out across my 20 cores…
Maybe FS2024 will be better…
