why do you want x-plane 12?

"Although most updates to DirectX are iterative, DirectX 12 represents a massive shift for the API Microsoft has been developing for several decades. It can massively improve performance in your games, and it has a few unique features that DirectX 11 doesn’t have access to.

It’s an important distinction between DirectX 11 and DirectX 12. In short, DirectX 12 allows game developers to target optimizations closer to the hardware, reducing the overhead incurred from the API and graphics driver. In turn, it’s also more difficult for developers to work with.

At launch, DirectX 12 actually showed slightly lower performance than DirectX 11, mainly on the back of its complexity. However, developers have targeted DirectX 12 more — ahem — directly over the past several years and squeezed out more optimizations. As we’ll get to next, DirectX 12 performs better than DirectX 11 in most games.

"The only exception is if you have an older PC dating back 10 or more years. Older hardware may run smoother on DirectX 11, or DirectX 12 may not provide much of a benefit at all. The vast majority of people, however, should choose DirectX 12 for its more extensive features and better game optimizations."

This has been discussed in the discord-chat with the devs. DX12 isn't the big win/gotcha you think it is. Not better than Vulcan, both having cons and pros.

exactly what the article I have linked said. except that Nvidia Framegeneration is DX12 exclusive. and Vulcan is less stable:

You answered about the advantages of DX12 vs DX11. That was not the discussion. XP is using Vulkan. And Vulkan is multiplattform, DX12 isn’t. DX12 and Vulkan are both of the newest generation and more or less similar. So I am asking the question again: why do you want DX12 in XP?

The post I mistakenly posted was not meant for you and I took it down.

and I am saying again:

Vulcan: less stable (unless that was just another xplane bug) and no Framegeneration.

Both Vulkan/DX12 are low profile APIs and both can suffer a device loss, it depends on the specific implementation.

So yes it was up to Laminar to fix them, I have not seen one in ages personally.

Frame-generation for Vulkan is a matter of short time, FSR3.1 is coming.

You could argue that DX12 gets the new shiny toys stuff first, it is mostly thr case indeed, but Vulkan will always get them shortly after, it's the nature of this industry.

Just like DX12 supported ray tracing & mesh shaders first & about a year ago or more Vulkan as well, Laminar even publically mentioned they are on the road map.

DX12 is made by Microsoft for Windows. 
That’s enough to make me cringe, already.

X-Plane is multi platform. DX12 for X-Plane will never happen. I don’t know where people get this idea that DX12 is more stable than Vulkan or Metal. I run X-Plane on windows and Mac, and have had no problems.

Well all I can say is that DX12 with Frame Generation has been transformative for me compared to DX11. Night and day fps and smoothness. Cant say I care much for the DLSS thingy so I stick with TAA. EDIT. If you guys get FG in Vulkan you are going to be blown away.

does it fill in the black bits (5 year old video)

or does it suffer from the same issues as way back then?

I tried FG with the new scaling tool and it‘s a game changer. Works with literally every „game“ so far. No DX12 needed 😊

After searching about this topic, it seems that DirectX is smoother and more stable, whereas with vulkan you may hit a slightly higher framerate.

If a game is being develop for multi-platform, then it is going to be vulkan for obvious reasons. Some developers will give you the option to choose between Vulkan or DirectX. DirectX is very important to Microsoft/Xbox thus it will have the latest and greatest features first. They have new updates like, DirectSR, "developers easily integrate FSR, DLSS, and XeSS upscaling into games" and more AI features coming in the future.

I have gotten the vulkan error in xplane many times. In my opinion, it is an issue with Laminar's implementation of the API.

I don't get it. What about it makes you cringe? That it is made by Microsoft or that it is for windows only?

Does it also make you cringe that "Metal" is made by apple and is for apple devices?

No issues or artefacts for me whatsoever. Just a massive fps increase. Whatever was available five years ago couldn't be the same thing. (Think it's NVidia 400 series cards only but I could be wrong.) I'll be honest Sparks, I've had thirty five years of 'miracle' fps boosters and tweaks which turned out to be placebo or dodgy at best. But this one, well, it works!
