Microsoft Flight Simulator 2024 needs 64GB of RAM for ideal performance — oddly, the game install size is only 30GB (www.tomshardware.com)

Technically correct, but if I'd have any input into hiring a person whose background involves making a flight simulator requiring 64GB RAM, that doesn't emulate every mol in that plane for that cost (I'm exaggerating a bit), I'd ask many questions.

It requires 16GB RAM, which is perfectly acceptable. But it can use more if available, for high res textures I assume. Which are streamed from Microsoft's servers, explaining in part the difference between install size and max memory requirements.

My guess is the big video ram is high resolution textures, complex geometry, and a long draw distance. I honestly don't know much about video games though.

The smaller install is totally the map streaming stuff. I'm unsure quite why it has to be so big, but again, I don't know video games. I do recall you having to tell it where you want to start from and it'll download some stuff there.
