+1, same thing happened to me during the Alpha which is why I couldn’t play it either.

This time, I bought '24 on Steam and it CTDs between 87-90%

Same issue. Repeatable crash every time at 87-89% load of world data.
I could never get the tech alpha to load/run either, which should have been a sign to me I guess.
Regards

Same issue, 87 - 89 % Loading world data, Sim hangs and then CTD.
Same error codes in the event viewer.

Basic specs:
Win 11 23H2 with latest patches
Threadripper 3970x / 128 GB RAM
GeForce RTX 2070 Super OC using latest drivers
Sim installed via Win App Store / XBox App

Exactly me re: The Tech Alpha. Was really hoping to not run into the same issue on Steam for the full release, but here we are. Surely the same/related issue

Also getting this with a Threadripper 5995WX, also know someone with a 2990 getting the same thing. Wonder if it’s a TR thing?

Same issue, but have i910980 RTX 4070

FWIW, nothing overclocked, NEVER get crashes of any sort, fresh Win11 install, clean booted with all apps disabled, all latest drivers, etc, etc. Also, I refunded on steam, but have gamepass and get same issue.

Hi, i had the same issue and myabe i found the cause: all users repoting this issue in this thread have CPUs with a lot of cores/threads.

My Setup is 2x Xeon E52680v2 with 10 Cores / 20 Threads (40 Threads in Total). I deactivated Hyperthreading in BIOS and now it works. So it may be that FS2024 can’t handle so much CPU-Threads. So 20 Threads seems to work (for me) but 40 Threads are to much.

Interesting…I have 36 cores with my i910980…will try and report back results

I tried everything and I think it’s AMD TR problem. I have Intel based PC and works fine but on my AMD TR pc will CTD at 87 - 89% every time. 2020 never had this problem .

I have this same issue as well. Resolves to a STATUS_STACK_BUFFER_OVERRUN in the event viewer. I also opened a ticket in zendesk but so far I’ve tried removing/reinstalling all video/audio drivers. removed all msi dragon and amd apps (from a FS2020 thread that had the same issue) and a zillion reboots etc.
I’m unable to find the conflict if there is one, so waiting on a patch hopefully, but i don’t see a ton of references to this issue. it took me all day to find this thread.

FIXED. Just reduce your high core count to something like 20 (mine is 36 cores) and it will work!!!

How to Set the Number of Cores in Windows just follow these instructions. You may be able to get away with more than 20, who knows, but 20 works for me.

This worked for me as well. I set it 32. Obv not a full fix since it degrades the computer for everything else, but FS2024 is running now until they can patch!

Looks like the hyperthreading fix above also addresses this in the same way, so pick your poison.

Can confirm, setting windows to 32 cores worked for me

The same with me: I have 18 cores
Using now 15, all problems gone !
Thanks for the hint !!
bye, walter

So, it seems Asobo only spends potato computers to their developers? Come on, this is a bad joke, isn’t it? One of the improvements over the MSFS 2020 is better multithreading (which can already be observed during startup until it crashes). Now we give the Sim some cores and it cannot handle it? Sorry, but having more than two cores is not so uncommon today…

Seems it doesn’t help to set core affinity for the process on startup. Throttling the whole system is no feasable option for me. Reading that the issue was already known during Alpha phase makes mit kinda upset…

I’ll test the workaround and report back… Just for testing purposes, this is DEFINITELY not a solution for me. There are reasons why I spent 2k€ just for the CPU and I won’t throttle my whole system just to get the Sim running…

Asobo, please confirm and fix it asap…

Can confirm. I disabled 3 of 4 CCD in the BIOS, so, 8C/16T remaining. Then the Sim will start.
Back to 32C/64T, Sim crashing again. So, playing 2020 and if Asobo doesn’t get it right soon, going for a refund.

Have a TR 3960 with the same CTD at 89% due to same stack overflow issue. 48 cores with HT on. Just want to make sure this bug gets attention and is addressed, because I don’t want to adjust core count and reboot every time I want to load msfs2024

Wasted 14 hours, configured drivers, BIOS, swapped PCs and removed PCI cards. But never had the idea that Asobo might simply have forgotten to test their product on powerful computers! And always thinking into the wrong direction: That the server issues were the culprits. Thanks, Asobo and MS.

Anyways. I made some quick tests on two systems:
AMD Ryzen Threadripper PRO 7985WX (64/128 cores) - SYS1
AMD Ryzen Threadripper 3970X (32/64 cores) - SYS2
It would be amazing if someone with a larger processor count than 64 cores or on an Intel CPU would also provide some test results.

Both systems performed a CTD during load since 2024/11/20, mostly at around 87%. The whole system stalls during the CTD on all threads. (!!!)

System Cores/Thr. Result
SYS1 64/128 CTD
SYS1 32/64 CTD
SYS1 16/32 CTD
SYS1 32/32 OK
SYS1 33/33 CTD
SYS2 32/64 CTD
SYS2 16/32 OK
SYS2 17/34 CTD
SYS2 32/32 OK

Please note that 16/32 does not work on the 7985 but works on the 3970. If it wasn’t like that, one could quite clearly think that MSFS24 is not able to run on more than 32 logical cores. Anyways, since HT is less powerful than real cores, we can draw the conclusion:

Due to a serious bug in MSFS24, make sure you don’t use more than 32 logical cores. If your system has more than 32 cores, you also must turn off hyperthreading.
