VRAM optimisation - the game can take nearly 20GB of VRAM if not more...

Sure there is. Again just look at this game over the past many years. You see it growing in graphics improvements and consequently hardware demand. Why wouldn’t that trend continue?

The ultimate goal of a simulator's graphics is a photorealistic image.

Certainly that’s the goal. And DCS is far far short of that!

You appear to severely underestimate just how hard graphics programming is. Less so with high level APIs like DX12, very much more so with Vulkan, which is a low level API where everything is programmed and optimized "by hand". 

This makes Vulkan seem like a step backwards, if this is the case why use it at all? Indeed another PC flight sim recently adopted Vulkan and honestly I saw no real performance or graphical improvements. Then it’s graphics were completely obliterated by a competitor using DX11. I’m sure ED has a sound reason for going with Vulkan though.

Because “hard” is not the same thing as “bad”. Quite the opposite in some instances.

You use Vulcan, in particular, because it allows for optimisations that are not available with higher-level layers. This does not inherently translate to “looking better” but to cleaner code, more headroom, better balancing, or just easier interfacing with other parts of the engine. For DCS, in particular, it could go hand in hand with some future CPU optimisations (multithreading being the most hyped one), which would yield improvements in areas that have no relation to the visuals… only everything else.

So in other words, there is no such thing, just like he said? What a weird way to try to contradict someone: by just saying “no” and then saying the exact same thing they did, as if it this somehow refutes the (very same) thing they said.

Yes I do fly in VR, my rig is in the sig, PD 1.2, no AA. I mostly fly F-14 and it's ok for most of the instruments but some are unreadable ex. TACAN digits or gun counter. It gets better with higher PD or AA but still lacking. I can't blame gfx engine here bacause it's simple lack of display resolution. This is 2K. You won't get better results even displaying neat still image. If you have at least 4K like HP Reverb G2, Pimax or Varjo you don't have this problem.

Let me expand on my situation, I use a Pimax 5K system, and I have the problem becuse of system settings. Crank the pixel density up and it takes up a lot of resources part of the basic problem is how DCS currently handles VR.

ED plans the switch to better utilise our HW (meaning get more performance from the same HW) and to have more freedom in development.

This kind of hints that the way DCS is, that it isn't making the best use of our hardware which is what I have been claiming.

I never argued with that. Only with the statement that DCS somehow shows you things wrong way so you can't see the cockpit clearly. And I still say it's not DCS gfx engine's fault.

the dcs engine will need to be altered to use Vulkan. Then we have this thread about improving how dcs handles vram.  I do call the dcs engine inefficient because it doesn't make the best use of hardware and it needs to be tweaked.
