Understanding Memory Usage (RAM + Virtual)
I was just looking at the LSM report and it shows that my city is loading ~39GB of RAM memory and another ~43GB of Virtual Memory.

I have 64GB of RAM installed so I'm curious about why would I need that amount of Virtual Memory since I still have effectively an extra ~20GB of free RAM.

Can you help me understand what each of those values mean?

PS: Thale, if you are reading... thanks for putting together such an essential mod :)

@Strictoaster In your case, Cities.exe has committed 43 GB of memory. Here committed means pretty much the same as allocated.

Of that 43 GB, 39 GB is in active use and kept in RAM. The rest (4 GB) resides somewhere else, as decided by the operating system. In your case, 'somewhere else' is probably not the page file because you have enough RAM.

So, we can guess that the remaining 4 gigabytes are nowhere: it is committed but not yet accessed memory. In virtual memory, reservations are almost free as long as the memory is not accessed. It's like a reservation in the books, waiting to happen.

Thank you for your remarkable work for the user communities!

I think I understand it better now, thanks for the clarification :)
