With DX12 coming at long last 
YEAHH means that the sim won’t be single-core and will utilise more cores and better performance and also since its DX12 opens a new world of options and will also start to use more of your Vram if not all of your Vram.
But as I’m reading around and thinking, My GPU, the 1660TI is going to poop itself. Meaning that I might not even able to run the flight sim anymore as it’s a 6GB card and really need a 2000 or 3000 series with more than 8GB VRAM.
Buy a seriex x instead! A true bargain where you never have to be concerned about ram-performance and so on
What specifically has made you think the GPU will “poop itself” with DX12?
It’s not likely to need more VRAM unless you turn up the visual quality settings.
We’ve seen it with P3D. Still single core.

As I have already read here several times and as they stated in theyre Q&A, I do not assume that we can expect real multicore support here. I think nothing will change in the CPU utilization (see P3D as an example)
Nor do I think the performance will change noticeably.
As has been said before, the developers are apparently more concerned with more eyecandy, at least at the moment.
That means with DX12 more effects come into play like better lighting; dust effects, better fog and so on …
I rather hope that there are no disadvantages with DX12 as you can see in some other games (Battlefield 5 and so on), which sometimes even run better and often more stable in DX11.
But to reassure people, if a game with DX11 is running on your current system, it should continue to work on DX12 as long as your graphics card supports it.
Maybe we even see a setting like there is in other games that lets us choose between DX11 and 12.
So I first expect nothing and let myself be surprised.
I hope Asobo will implement both DX11 and DX12 to choose from as many game developers do. But I’m afraid they will not.

The only reason to maintain two rendering backends would be to support video cards that were supported under DX11 that don’t have DX12 drivers. I don’t know if that covers any of the actively supported AMD or NVIDIA GPUs.
I am on a 2060 Super with 8 Gig VRAM but I do not get my hopes too high.
I rather expect the requirements for a PC to run this simulator to go up…
IMHO there’s been too much emphasis placed on DX12 vs. DX11 - 12 is not the Holy Grail. It’s all about the code. DX12 has the potential to bring better performance, but if it’s not coded right it’s going to have issues just like 11.
You may be surprised to find that - after the update to DX12 - your older card runs even better, because coding may be improved to better utilize multi-core CPUs, which in turn will handle instructions to the GPU more efficiently.
The bigger questions are: how’s your CPU and system RAM? Got an SSD?
you cant compare the 2 games when do you get some real info?
1660TI series and also the 1660 super does support DX12 however only at 1080p then again would not expect to go 1440p. Able to run p3d V5.2 just all good, Do get CTD from going over 6 VRAM but only happen to me twice and that was before 5.1
Do wish it’s more cores then singl core as I have an i7 10700K with 32GB ram all on SSD
I know. But P3D shows that DX12=Multicore isn’t necessarily true.
Karl
The main reason to support DX11 aside DX12 is flaws that will show in the DX12 versions. As an example many P3D users would stick to DX11 because of extensive VRam usage in DX12 in P3D.

Ok have to ask because I don’t see info on DX12. Xbox has DX12U capabilities, nvidia 20 and 30 series cards have the DX12 12_2 capabilities, but the 10 series only to 12_1. Missing is the following: Ultimate brings to DirectX 12 Raytracing, Variable Rate Shading, Mesh Shaders and Sampler Feedback to hardware that qualifies for the DX12U badging. I also understand that an application using DX12U will work on cards with just DX12, but don’t get the enhanced features like above. Feature levels in Direct3D - Wikipedia
Can @ASOBO add some info about DX12 versions to the FAQ?
Edit: would like to add this to dev q and a June @Jummivana

Unused vram is wasted vram
I have the same gpu and you should have no issues.
DX12 will work on any modern gpu Turing,Ampere and AMD similar gpus.All those GPU are DX12 ready.
Anything older like pascal 10series it will work but those aren’t DX12 ready or supports features like rt,dlss.
The developer has to optimize for vram use not the API.
Dx12 doesn’t work the exactly same in every game.You should be ok.
That’s not very good advice…
OP already has a decent computer. Investing in some upgrades is certainly going to be more benefitial than buying a completely seperate console.
I don’t know what makes you think RAM performance “and so on” won’t be a concern for consoles, but you might be in for a bad surprise a while down the road.
I really dont know how they make it work with RAM, we all know that the sim can easily use 16GB RAM. There must either be heavy downgrades in scenery-detail or texture resolution or other optimisations.
The Series X has “only” 16GB RAM, but its pretty fast DDR6 RAM.
BUT only 10GB are used for Graphics, 3.5 as System-RAM and 2.5GB are reserved for the operating-System.
On PC, most users have atleast 16GB or even 32GB RAM and a separate VRAM of around 6-12GB VRAM on the GPU, or even more on the newest 3090 cards.
On my RTX2080Ti, i have 11GB VRAM and they absolutely get used when flying in big cities. So, either they have done TONS of optimisations or they reduced the settings for the Consoles quite a bit…
EDIT: The DDR6 RAM is so fast, thats probably the reason it doesnt need much of it.
Uhm wow…
Memory. 16GB GDDR6 w/320 bit-wide bus
Memory Bandwidth. 10GB @ 560 GB/s, 6GB @ 336 GB/s.
To give some comparison DDR4 2933 bandwidth is 94GB/s
Yea, that RAM is fast, blindingly fast
