Will DCS support nvidia frame generation and dlss 4?

Nvidia does market frame generation as a DLSS technology, although in my opinion that is a marketing-driven decision, to improve acceptance of frame generation due to how strong the DLSS-branding is.

But it can make it confusing, and it is better to explicitly specify whether you are talking about upscaling or frame gen, rather than use the word 'DLSS' and assume that people will interpret it as merely referring to upscaling.

Its what happens when people have a little bit of knowledge, im lucky in that ive been a member of GURU 3D for over 15 years and there are some crazy knowledgeable people on there and some very interesting topics, the guy who wrote MSI Afterburner is a staff member and some top end private custom system builder are regular posters.

For me DLSS 4 using Version K has improved the visuals of many games and obviously there is also a performance boost, other games to me look no different but DCS at 77% DLSS still looks amazing and smooth at Max settings and 4K is always over 100fps on a 9950x3d/4090@3ghz.

Something like Ready Or Not looks no different, Metro EEE looks better i think. As for FG, maybe it looks better on CP2077 but on other games i have it off.

Hi,

DLSS 4 is something we will look at once we have vulkan implemented in public release version. 

thank you 

Hi Bignewy,

Not to nag or anything but ED have been talking about Vulkan API (and possibly DX12) for years now. It's been a LONG time.

Still no cigar.

Not trying to be annoying, but any chance of seeing a Vulkan or DX12 Open Beta sometime in maybe the next couple years? (Again, not trying to be difficult.) It seems to have a lot to offer and I'm surprised that a sim on the level of DCS is still using what in 2025 is an archaic graphics engine that can't make the best use of today's awesome hardware. Ghosting-free DLAA/DLSS, hardware raytracing with nice lighting and shadows, frame gen, better use of video memory and all that good stuff!

You've had us foaming at the mouth for years now!

I maybe mistaken, but I think you need at least an uptodate version of DX12 to support frame generation.
DCS won't be developed for DX12 since it will be making the jump from DX11 to Vulkan.

So bottomline - Vulkan is in developement anyway and until its done, there will be no upgraded feature support (for GFX).

At least this is my understanding. Please correct me, if I got something wrong.

Hi,

Vulkan is in progress and as I am sure you have gathered its a huge task, I do not have a release date currently, when it is ready we will share more with you all. 

thank you

Thanks  We're all looking forward to it, I bet it's gonna be pretty kickass and will allow our hardware to stretch its legs more

I could be wrong but the impression I got was that ED were developing new graphics engines for both DX12 and Vulkan API.

I think they initially intended to do both IIRC, but then only went for Vulkan. Good decision!

We are only working on vulkan going forward, it allows for more possibilities over DX12

My understanding is that DX12 is easier to learn, but Vulkan API has the potential to give better performance on a given set of hardware. I'm not a coder though. Vulkan also still supports DLSS/DLAA, Frame Generation, hardware-based raytracing/path tracing and ray reconstruction and all that good stuff so it's as good an approach as any! I'd love to see all that great stuff implemented in DCS because the current DX11 graphics engine doesn't make extensive use of all the modern goodies in RTX 40 and 50 series GPUs.

Once they gitter dunn though, it's gonna rock.

That's cool, I'm just curious what the differences are? My understanding is that they both support the latest hardware graphics functions but DX12 is limited to Windows whereas Vulkan can be coded for any OS and is non-proprietary.

Less overhead done right.

Yeah, that's what I heard. It makes life less stressful for the CPU (and it seems to me that CPU usage in DCS is very well-optimized now, it's just too heavy on GPU usage and I'm not sure how Vulkan API affects GPU load for a given scene complexity)

AD

Edit, and speaking of less overhead, I'd LOVE to see frame gen and DLSS implemented without ghosting! I'm hoping it's because of DX11 and not an inherent limitation of the tech because it works well in other games, but forcing frame gen and/or DLSS in DCS World causes a lot of annoying ghosting and artifacts.
