in development Vulkan API Discussion

Just to clarify, I have no problem with that, in fact, that's exactly what I've been saying. Get the MT preview polished up, get it ready for Stable, and you can then make another preview branch with DLSS, for instance. Rushing changes this big never ends well.

MT is still running in a preview form and is being tweaked with the feedback and reports we have had from many people. We need time to get MT to where we are happy, then we can look to the future features like DLSS and Vulcan. We will share news when we are ready of course. 

thanks

This is the way!

Having bugs on the experimental option is not such a big deal if there is still the standard option with DX11 and ST. Personally, I'd rate Vulkan support at much higher priority than DLSS (or FSR) since it provides the basis for the next-gen engine, but of course that's only my point of view. Don't know how they set the priorities internally.

DLSS it can be only implemented in Vulkan or DX12. Not in DX11 !!! so Vulkan would come first than DLSS.

Hm, I'm not sure about that. The Nvidia website indeed states that it's only available on DX12/Vulkan.

However, there is at least one game (Assetto Corsa Competizione) that I know of which supports both DLSS 2.0 and FSR 2.0 and although based on UE4, it's DX11 only. No DX12, no Vulkan. Maybe DLSS 3.0 is DX12/Vulkan-only?

Well, they shown a video stating it was done using MT and DLSS, but nothing about Vulkan. This suggests they got it working in DX11 somehow.

Well,

one *could* import the engine to DX12 Devkit/Libraries as MS has said, and continue to run the engine in DX11_x Mode under DX12's API, thus giving someone access to DX12 Specific Interfaces and Tools, while still running their DX11 Based Engine.

You just wont see any Performance or FPS Improvements running in DX11_x mode, as the engine would have to actually be re-written to take advantage of those things. (DX12 Low Level access, DX12 Multi-Threading, Asynchronous Shaders and Rendering, etc etc etc.

P.S. DLSS 3.0 is DX12 Only, DLSS 1.0/2.0 works on DX11_1+, So there's that too.

That's probably it. I highly doubt they'd implement 3.0, given that it'd require a 40 series GPU to support it. Given how overpriced they are, most people will be on 30 series or lower, so it's most likely DLSS 2.0.

DLSS3 introduces frame latency, something we don't need in DCS

Well, I wouldn't know since I'm on a 1080ti, anyway.  Not to mention it's been implemented in what, one game? I think it was in this recent Spiderman thing.

What kind of increase in performance would Vulkan give?

I'm sure it's system specific, but is there a rough guess?

15%

In VR, it could nearly double, since DX11 renders the whole scene twice, while Vulkan does it in a much smarter way. For screens, I don't know.

FSR should work on a 1080ti as well, iirc. Since they also said they'll implement FSR, that might be an option for you.

Pretty sure that'll be very system- and settings-specific, just like multithreading. So I don't really think we can estimate numbers here.

Cannot help myself to check if ANY update under "Official Updates" every a few hours since MT beta launched. 

Expecting stable version coming soon, as well Vulcan/DLSS for next. Cheers ED team! Dreaming for DCS growing into Unreal5-like next gen platform someday. 

@DigitalEngine already got update of “preview” MT as part of stable version right after that post. Love it though still some bugs which I can accept given the huge performance boost from last Dec ver.  thanks anyway. Wish to see a “official” road map but I understand it’s a challenge to ED team.

When can we expect to see it introduced in DCS?

Hope soon™, and specially I hope it's not longer than this year. MT was huge task and not finished yet, that's for sure, but It's about time we finally see what Vulkan will bring to us.

Will be nice for those of us using VR. I'm sure ED would love less forks to maintain too.

With stable being updated, I think we might be nearing the appearance of Vulkan in public beta.

MT has not complete release yet, has only the test version, and we need waiting to a "2.9" MT final release before Vulkan comming.

MT is no where 100%, just because the preview was included on the stable branch doesn't mean it's done,
If MT was 100% ready, it would be the only binaries included in the builds.

There are plenty of problems with the current iteration of MT. ED decided to incorporate them into the last 2 builds of the Stable build because they are not game-breaking (although they can and do lead to crashes).
Going to Vulkan now/soon (before those issues are properly fixed) would be a troubleshooting nightmare for them, since they won't be able to tell if bugs/performance problems come from MT or Vulkan, or a combination of them.
Let them get MT stable (not DCS-lingo "Stable" but proper stable) before adding new stuff on top of it

Vulkan has nothing to do with MT....
