Phoronix: VKD3D 1.3 Being Prepared For Release

While the VKD3D-Proton downstream gets much of the spotlight these days for the Direct3D 12 API implemented atop Vulkan for use by Valve's Steam Play (Proton), Wine's VKD3D continues to be developed and is closing in on its v1.3 release...

One of the features I would like is DirectML. needed for a few compute programs that would be really nice to have

So HLSL shader compiler will be finally ready?

Out of curiosity, which ones?

Test benches of DirectML I've seen have been disappointing, but I don't actually know of any user-facing apps that need it.

Off the top of my head, would be topaz labs VEAI. but thats all I can think of atm lol. but its a good one imo

Is there any effort to upstreaming the work in VKD3D-Proton (similar how to many Proton changes get upstreamed into Wine) or are they pretty much fully separate libraries at this point?

Oh yeah, I forgot about the Topaz stuff. IIRC the project its derived from, SRGAN, was based around CUDA/pytorch, and some of the other active derivatives (see this, this, and this) use ncnn/vulkan backends. I think you'd be better off using those kinda projects on linux, especially if you have a Nvidia GPU.


Open-source upscaling that actually uses adjacent frames is a bit behind VEAI, last time I checked. You don't necessarily want that though, as sometimes its better to leave the inter frame processing to less janky traditional filters.

lots of work gets upstreamed. but since people don't understand the difference between the two ill explain it. Wine is used in commercial and enterprise (like crossover) software . this means they have stability obligations to keep. even on staging branch. You can think of "wine-staging (vkd3d included)" as a testing branch, and vkd3d-proton as a rolling release branch. but even without obligations, the end goal is still accuracy.

there is another distinction, vkd3d-proton houses a bunch of hacks that will never get accepted upstream that greatly help gaming performance. but can hurt conformance. which means this would actively be a bad think for wine to upstream. (as their goal is conformance) (Think of android emulation or early dolphin emulation where their are Emu and EMU-MMJ)

VEAI is actually pretty darn good. it all has it's uses (mainly for AMD LOL) but it also has somethings it beats out on, somethings it looses on. with AI upscaling there is no "best answer" just "this one worked the best for this input"

but there are other examples but none that I remember, so maybe not good ones

I was wondering that myself. I thought everything was open source and upstreaming was just a matter of timing. So that Valve would develop something and put it into Proton immediately, and regular Wine would incorporate it a few weeks or months later.

Can some knowledgeable poster let us know how the development of Proton and Wine are integrated or not integrated? I'm confused.
