Why is FS2024 virtual memory usage so high, when so much additional RAM is available?

Someone correct me if I’m wrong, but my understanding of virtual memory is that it’s saved temporarily on the hard drive (in my case SSD) in order to free up physical RAM space for more “immediate” purposes. But in the recall of that virtual memory (loading it back into RAM) there will always be a performance hit because that data will have to be read from the hard drive.

There’s no way for me to know specifically what data MSFS2024 is loading into and out of virtual memory, but I’m surprised that it’s using ~15GB of virtual memory and only ~9GB of my physical ram, when I have 64GB of RAM available. Wouldn’t my performance just be straight up better if MSFS actually loaded all of this into RAM?

Here is a picture to show that allocation, just flying around the mountains with not much scenery nearby:

The virtual memory consists of RAM, VRAM and Pagefile. There was a deep in explanation of virtual memory usage in one of the developer streams. You should be able to find using the search function.

Thanks, I found it here: Page File Usage - #14 by TenPatrol

The wording of the FPS debug confused me as someone with a background in computer science :joy:.

So in my case in the screenshot it’s:
Physical + GPU: (9.606 GB + 6.215 GB) = 15.821 GB
so actual page file usage is 16.15 GB - 15.821 GB = 0.329 GB

So very minor page file usage!
