DXVK [GitHub], the awesome Vulkan-based D3D11 and D3D10 implementation that's used in Wine and Steam Play's Proton has just put out version 0.90 after the latest release of the Vulkan API.

As mentioned in the weekend roundup (typical of this to happen just after…), the Vulkan API now has the VK_EXT_transform_feedback extension supported. This does require you to update your GPU drivers. To quote my own article since it's important and I don't want people to miss it:

NVIDIA have already pushed out 396.54.09 of their beta Vulkan driver to support it, along with AMD's RADV for Mesa getting a bunch of patches for it and Intel's ANV driver also getting patches.

The biggest addition in DXVK 0.90 is support for Stream Output, which fixes rendering issues in a lot of games when run in Wine with DXVK. Here's what the developer said:

Implemented Stream Output (#695#135). This fixes rendering issues in a lot of games, most notably missing characters or NPCs in Unity Engine-based games and The Witcher 3, Nvidia Hairworks in The Witcher 3 and Final Fantasy XV, as well as issues in Quake Champions, Overwatch, and other games.

As for bug fixes and improvements, here's what made it in:

  • Assassin's Creed Odyssey: Slight reduction of CPU overhead
  • Bioshock: Fixed race condition in D3D10 mode (#655)
  • Dark Souls 3: Fixed bug causing resolution changes not to be applied correctly
  • The Evil Within: Fixed regression causing random geometry to be rendered

Really amazing progress as always, can't wait to see this included in Steam Play seems like it's going to be quite a difference. It doesn't seem like there's much left for DXVK to do, although there's no doubt small performance improvements could still be made with enough time.

Dark Souls 3: Fixed bug causing resolution changes not to be applied correctly

Just picked up DSIII and ran into that bug so that's great news for me :)
Is Stream Output the feature that LIS: Before the storm needs for to be rendered properly with Vulkan?

I gave it a test run following the guide on github, excellent work :)

A couple of screenshots showing Vikings: Wolves of Midgard at work. This is a Unity game and previously both the main character and none of the enemies were visible.

Since it's Unity Engine, yes.

Pretty much everything using Unity should work fine now.

Outstanding work!
Its amazing how fast we move forward.

Great day for DXVK! :D

You forgot to clarify that Wine needs a patch to make Stream Output work

Yes, but it's mostly irrelevant now that we have the Feral port. Great news for non ported games though.

But the Feral port is using the obsolete OpenGL.. I guess now they can update the port for to use Vulkan instead.
YoRHa-2B 13 Oct 2018
Why "obsolete"? It works, it's supported natively by the engine, and it appears to be more than good enough for the game. No need to port it to Vulkan.

The API choice will be much more interesting for LIS2 which uses Unreal Engine 4.

So has this resolved the last major issue in The Witcher 3? Or soon™?

Witcher 3 should work fine now.

"Most notably missing characters or NPCs in Unity Engine-based games and The Witcher 3"
so, looks like some people were playing witcher 3 missing content (npc) without even realizing it supose to be there...

In Witcher 3 it surely works, looks rather nice I must say as well, except it killed my fps by 10-15 :p

I just spent over an hour in Vikings, Stream Output works like a charm :)

Congrats to everyone involved! Time to play The Witcher 3 now. I wouldn't use hairworks in TW3 though, it's known to have hardware acceleration only on Nvidia, so save your CPU cycles for other things.

Hm, for some reason code tag here messes up whitespace.

Hm, it doesn't show up in the Wine run though. I guess something is still missing.
