I don't think the impact will be nearly what it's been hyped to be.  There will be some significant impact, but once again, I'm running nearly all settings at ULTRA 100/200/200 8x/16x on an 8Gb card.  I don't believe MS/Asobo will want to vastly exceed what 90% of their user base can accommodate in the way of VRAM.

The other reality and it's huge:  many sliders hardly impact the visuals anyway.  One can dial back certain sliders for example affecting shadow quality, the impact will be very significant on GPU and VRAM utilization, and yet you can't even tell you changed it from Ultra to High.

Until you run many large add on AP’s with tons of PBR textures, full live traffic and a texture heavy add-on AC like PMDG Heavies..

Easy to say now on a very stock sim...

Stock P3dv5 runs great on 8GB VRAM!

Yes and stock P3D is using DX-12.

I believe 16Gb of VRAM will be ample for MSFS post DX-12 until you start increasing the render scaler beyond 100, which I won't do anyway as it adds virtually nothing meaningful for the cost involved.   And that is w/ the addition of PMDG heavies.  I will try to find a 3080Ti w/ 20Gb if that's what it ends up with to have certain headroom, but again very likely 16Gb will be good enough, IOW good enough to let you keep all settings at Ultra and never have to stop and adjust. 

I have FSDT's KORD installed which utilizes all PBR textures, and note both VRAM utilization and the main thread in the CPU, LP16 is running at only 52%.  My aircooled, hyperthreaded 9900K at 4.9Ghz all cores is running at a very low 50C.  The 2070 Super is almost maxed out of course, but not quite yet (evidenced also by the solid 30fps as it is vsynced to 30Hz) and the texture surface areas involved are huge at KORD compared to the PMDG 777.  This is with all sliders to Ultra except a few shadows and reflections set to High instead of Ultra.   You can see the CPU also has massive headroom to accomodate the CPU-intensive PMDG heavies.  

So yes, 16Gb will be sufficient, and the 9900K will be sufficient, to run MSFS w/ the PMDG heavies very likely maxed out, never needing to stop to adjust.  Of course, a massive part of this is letting the machine deliver only 30fps.  But it is an ultra-smooth, stutter-free experience, w/ no screen flicker, significant mouse lag, or any other detriment to the best possible experience at this resolution.  Perhaps if there is headroom in the new GPU we can enable better supersampling than the 8x offered in sim which is what I'm using now w/ my lowly 2070 Super:

Very nice...  Although all those gates are empty!

 

I wonder how it would run on your setup with a fair amount of AI AC parked at all those gates?

 

Also, what Rez are you running?

I value smooth stutter-free animation, and high image quality so the first thing that goes if that were jeoparized is too many AI AC.  But again, it's only an RTX 2070 Super 8Gb.  I would love to pick up a 3080Ti sometime but really can do w/o until PMDG and GSX arrive when, and yes DX-12.  I normally see several AI AC so not sure what happened there. 

Resolution is 3440x1440, the native resolution of my Dell 3415W curved screen.  

( VRAM is a bit off topic for this thread  which is actually about a CPU utility )

 

The Reverb G2 is 4320 x2160 native.

Though potentially rendering two very similar 2160x2160 images in 3D may save a bit of VRAM versus a flat 2D image of double the width, no idea.

It is also a 90hz display but that is another issue and should not effect VRAM usage.
