32GB is still enough for MSFS 2024 loading times.

No, 64GB won’t noticeably improve loading times, even with all addons.

Loading a flight is bottlenecked by your storage speed (NVMe SSD) and CPU decompression. RAM helps keep assets ready once you’re in the air — not get you there faster. A faster SSD or better single-thread CPU performance will cut load times more than doubling your RAM.

If you’re running so many addons that your system starts paging to disk mid-flight, that’s a stuttering problem, not a loading screen problem. 64GB can fix stuttering in dense scenery with heavy ortho and traffic mods, but it won’t shave seconds off the initial load bar.

Save the money for a better SSD or a CPU upgrade if loading times bother you.
