MSFS 2020 Crash in VR - HP Reverb G2

I just asked the question on a YouTube channel of a person who makes videos on MSFS with the HP Reberv G2 and an RTX 3090 if he had CTD.
A person just gave me his PC configuration and he doesn’t have a CTD

Hi, no CTD’s here running I9-9900K@5.0Ghz, 64GB Ram@ 3600 Mhz RTX3090 with HP Reverb G2

I notice it has 64GB of ram.
So these 64GB of ram, could be the solution to CTD?
Still the crash due to lack of virtual memory might well confirm it, although I did not find any messages like this on my side

EDITION: The famous Youtubeur just told me that he had no CTD with 16GB of Ram

Current System Specs:
STORMFORCE
I9 10900K (Running stock)
ASUS OC TUF RTX 3090
16GB RAM

I don’t know if we can draw a conclusion with 2 examples, but there are 2 people with Intel platforms, who do not have a CTD with RTX 3090, while DarkClown which has an AMD platform with a RTX 3090 at CTD

Crash to desktop without error message

I doubled the page file size of my manual SSD from 8 to 16GB and tried again. (but left the system SSD to automatic)
But this time I monitored the actual usage live while playing using the system resource monitor on a separate screen.
I also lowered the texture size in the game from ultra to high to see if that helps (and restart the game as recommended to take effect)

Take off from London city, fly around Buckingham palace
The game uses on average 10GB physical ram and 30GB page file.

Fly away from the city towards the south, I notice I have firefox open, so I close it.
The game’s physical memory usage goes down to 8GB, page file 28GB

Turn around, and fly to Heathrow.
When directly overhead Heathrow, Ram stays the same (8GB) even though there is some ram available, the game does not appear to try to use it. Page file usage goes up 30~31GB
The frame rate goes down significantly, but the game holds on.
I goof around Heathrow for at least 15 minutes, and the game appears stable.

I leave Heathrow, back to London city through London city center.
Mid-way through the transit, all of a sudden the page file shoots up to 34GB, the game slows down to a crawl, freezes for a second and CTD.

Windows event manager reports running out of page file and 3 seconds later the application crash for unknown reason.
I wonder if Windows automatic page file assignment could be freaking out when an application uses more than 2x physical RAM and would perhaps send some kind of signal to force MSFS to reduce page file usage (for which MSFS would fail and crash) ?

Crash to desktop without error message

I tried again with full manual Pagefile.
16GB + 16GB = 32GB total pagefile on disk (SSD)

This time I got lower memory usage when flying return London City <> Heathrow 1000~2000ft with 28GB pagefile. I also got better framerates.
Then I made a super low pass 200ft over the Thames river and this is where hell broke loose but the game did not crash. Framerate tanked, the memory usage spiked up to 39GB pagefile, the actual physical memory usage went down from 10GB to 7GB. But no CTD.

As I climbed out, half the city graphics went blurry as the game apparently couldn’t load any new data.
It took about a minute for the game to clean up the graphics and recover. I finished the flight uneventfully.

Thank you for your help.
I agree the memory usage should be the game’s responsibility. Especially for a game with highly dynamic RAM usage like MSFS. At this point, it’s not just an optimisation issue. It’s plainly taking huge quantities of memory without checking the memory budget.

I’m going to have a look at RAM prices to see if I get increase my computer’s RAM. This should help the situation and reduce the game’s reliance on dumping data to virtual memory on my SSDs.
