Continuing the exciting Wine-related news tonight, DXVK [GitHub] for Vulkan-based D3D11 and D3D10 implementation that's used with Wine has a 0.81 version now available.

Reminder: DXVK is one of the projects that makes up Valve's Steam Play. Enabling Windows games to run on Linux, directly through the Linux Steam client. Valve help fund the development of it.

Here's the highlights of what's new:

Improvements

  • 32-bit builds are now compiled with the dw2 exception model for better performance
  • Minor reduction of CPU overhead
  • Added configuration option to disable D3D10 support (set "d3d10.enable = False"). This can be used to let problematic D3D10 games fall back to their D3D9 renderer.

Bug fixes

  • Fixed occasional crash/hang when the state cache is enabled (#665)
  • Fixed potential violation of the Vulkan specification when copying images
  • Star Control: Origins: Fixed rendering issues when MSAA is enabled (#666)

While perhaps not as overly exciting as previous builds, every tiny hint of a performance increase through each release will add up to create a better experience for everyone. The level of work going into DXVK is seriously impressive.

Best part of it:

QuoteMinor reduction of CPU overhead (I know it's getting boring, but I swear I'm telling the truth!)

well done they fixed bug 666, must be a really diabolic bug.

If I'm not mistaken, there were about 30 commits for that +0.01 upgrade, from 0.80. Perhaps not roadmap-worthy stuff, but still a boatload of work it seems.

Number of commits doesn't equal the amount of work though.

Fixing that was actually a shitton of work, so it kind of lives up to its number I guess? On the bright side, it also makes depth-to-color image copies more efficient than they were before, so it wasn't exactly wasted effort.

More important is the other bug though, I thought it was quite rare, but apparently a lot of Lutris users started running into it as of late. FWIW, the fix for that bug was cherry-picked for the Proton build.

And yeah, things might be rather boring nowadays, but it's mostly feature complete and doesn't have a huge amount of optimization potential left.

Critical part in that release is #665.

A lot of good improvements, I've tested many games with DXVK and it is still amazing how well it works. Never thought I would spent some money for Windows games, but DXVK changed my opinion.

Keep doing your awesome work YoRHa-2B!

Thanks a lot for all your work spent on this. It is still magic that I'm playing GTA5 on my machine.

I have a small question: Next to stream output there is still "Predication" on your list with missing features. From my (limited) understanding this should only affect performance for games that use this feature (e.g. Arkham Knight wants to do so). Do you have a feeling about what you can gain with predication, assuming that it is actually possible to somehow translate this DX feature.
