I think some people are confusing RAM usage vs allocation. It's very easy to see that you have 64GB and the program in turn using 34GB of RAM or whatever number that can provide confirmation bias. Programs will happily allocate themselves copious amounts of RAM if its available but not necessarily use it which can give the impression that a program is a memory hog. However should another program require ram the windows memory manager will de-allocate that RAM and give it to the program in need. This is all assuming there's a large disparity between usage and allocation.

Using tools like task manager or `systeminfo` and observing RAM usage over a period of time (Not current) can give you a much better idea on whether you're going to start page filing or not.

Personally, I run a lot of programs. There's been a lot of tests done on these forums here, I believe a proper stress test done by Cpt Piet (I can't find his username) where he ran MSFS, with the run of the mill programs for simming plus photoshop and was rendering a video in blender. Something 99% of people won't do and barely saw 24GB of usage (from memory). To me 64GB is genuinely not needed and comes of more as a placebo than anything else.

32gb running VR and no need for more RAM with MSFS24 (so far), never a need for MSFS2020 with a fair number of background programs running.

Extra ram is always good and not expensive at least for PC. If you use VR and have Ultra settings you better get that ram for future prof you may get away with it with default planes but that will not cut it with complex 3rd party aircraft.

Rendering for VR is a matter of VRAM not RAM itself. A Quest 3 (for example) is roughly the equivalent to running the sim with 4K (a little bit more). Between 1080P and 4K you won't see a discernible difference in RAM usage but for VRAM the usage would be quite drastic.

I run the likes of Fenix (which has a pretty small VRAM footprint) and various other complex aircraft in VR without issue to my 32GB of RAM, honestly its hardly changed. my VRAM OTOH has increased by quite a bit.

For my use case, it is. Constantly seeing over 32gb allocation when using the ini A330 in add-on airports (4K Ultra settings in 2D and medium-high settings in VR).
