Even w/ a 3090 on board? The lowly 2070 Super 8Gb delivers liquid smooth MSFS thru really complex scenery and still have most all sliders and Ultra and about the only thing that threatens this is Ultra clouds in some scenarios, so it's already close to good enough.  My sense is when I upgrade to a better GPU I'll never need to adjust settings if the current behavior is any indicator.  I do need more VRAM for sure and more processing power for the GPU, but really performance per se is very close to a non issue, very thankfully.  And especially the main thread which in the worst places hovers around 70% (in the TBM930), but usually is bouncing around 20-40% utilization.   I hope when DX-12 arrives hopefully there will be even a little more headroom in the main thread for PMDG's debut in MSFS.  I'm astounded at how much better total performance is in MSFS over P3D 4.5.

Are you talking about a G2 here or something lower resolution like a Quest ?  ...  or not talking VR at all ?   VR is much more demanding than just using an old school 2D flat/curved screen.

To be honest even on a flat 2D setup my 3070 struggles to do "all ultra" at better than 35 -40 fps at 1440p  and a 4K monitor starts to really push the friendship for Ultra on a mid range card like my 3070.  Though at that point I am getting CPU limited and really hammering my i5 8400 on most of its 6 cores (I am considering a 9700 as a temporary upgrade with a MB and CPU upgrade later in the year when the dust settles on all the new CPUs) .

1080p on a 2D monitor is another matter of course, most new cards can run the game at 1080p fine.

the old tumb of rule, min system ram vram x 2 , that one is old when benchmark

Flat 2D 3440x1440.  This is where I get off the hardware chasing bus that is prevalent in these parts.  My lowly 2070 Super doesn't struggle at all unless I'm really getting into weather when I need to drop volumetric clouds to high from ultra.  It doesn't struggle because I don't need it to deliver more than 30fps vsynced to 30Hz, and the experience is more than excellent.  I think in truth, if I could bump up to say 11 or 12Gb of VRAM, and increase GPU processing power by say 15-20%, I'd be good to go.  I don't need a 3090, but still may get one for lack of a better choice.   I don't know how well this will hold up when PMDG comes on board, but then again we have DX-12 to factor in and I dare say not too many people can speak w/ any authority about what is ideal, enough, to run PMDGware in MSFS at 1440P at 30fps vsync to 30hz.  I don't believe 4K is worth the price of admission either.

If I understand correctly DX12 will provide better performance even on the newer GPUs? I thought it would improve especially for older cards?

Fair enough. I am sticking with 1440p for the time being myself.

It seems to me the people seeing genuine and worthwhile benefits out of 64GB ram are running a 3090 on a hi res VR headset like the Reverb G2 (with 2 displays at 2160x2160 each and WMR/3D software) .

I would love to see your dev mode performance numbers while sitting on either Kennedy,LAX,MIAMI,London airports in the A320,747 or 787,or complex cockpit GA plane.

With those slider settings...

I also noticed that when exiting VR without the headset asleep before with 32GB I was unable to do other things like browse the web until the HMD went to sleep.  This is no longer the case with 64GB

I can do this with 32gb, I believe that you found this difference, but I don't think it's because of the added ram.

It was literally the only thing I changed.  If you have been following this post the reason you can do this with 32GB of system ram is because you dont have 24GB of VRAM on your graphics card.

I'm only using the TBM930--does that qualify as complex GA?  I'm using MSI Afterburner/RTSS for numbers, but I can look at dev mode.

Yes the TBM would do

OK I will a little later right now I'm at FL190 heading for KDEN from CYYC in the lovely PMDG NGUx. ;o)

OK, now the lowly GPU which I stated is indeed insufficient at ultra settings no contest there.  I have clouds and reflections to High, everything else at Ultra, 100/200/200.   Note the RAM in use, and also the main thread (in MSI OSD) is well below 70%:  Bring in DX-12 and I think there will be room for PMDGware.

Mike, can you give an estimate what the total GPU performance impact is by adding the 2nd 32Gb?  Put another way, what is the performance deficit by not adding more RAM?  Also, what is the the theoretical view on how this will be affected by DX-12?  There is no way I'm going to install more sys ram when the sim never gets anywhere near using the 32Gb installed already.

I believe if this is how it runs on your system then don't bother. However if someone could lend you 32GB to try out why not just trying?

I put additional 32 GB and could not see any tangible difference honestly, but I am digging the extra RGB lights in the case so I will keep them.
