Wine 5.5 development release out with new features and fixes

As expected on their biweekly development cycle, the Wine hackers released the latest development version with Wine 5.5 out now with new features and fixes.

Quick reminder: Wine is the software that can help run Windows games and applications on Linux.

Here's the highlights of what's new:

  • Builtin libraries use the new UCRTBase C runtime.
  • Compatibility mode used when reporting Windows version.
  • Better support for debug information in PE files.
  • Support for linguistic case mappings.
  • More attributes supported in WebServices.

They also mentioned 32 bug fixes, some of which were fixed in previous releases of Wine that eventually saw some retesting. These noted bug fixes include issues solved for: Call of Juarez, Death to Spies: Moment of Truth, Adobe Flash Player, Might and Magic VI, Fable: The Lost Chapters, Audiosurf, Dark Souls 2, Wolcen: Lords of Mayhem (no more blob heads) and more fixes for games went in.

You can see the release notes here.

I've also been hearing lately about a lot of work going on to help with Media Foundation in Wine, as this is needed for quite a lot of Windows games to work properly on Linux with Wine. The Media Foundation API is used on Windows for various video and audio purposes and it's been another pain-point for people using Steam Play Proton (which uses Wine). You might find some games have no intro video, or a static background instead of a video and more—all of it getting slowly fixed up so it will be good to see that eventually done.

The ongoing MediaFoundation work is the current highlight for me. Apparently, a lot of modern Unity-based games without native support rely on that for video playback. I have set up a prefix with native (Windows 7) mf dll overrides, which plays these games just fine, but getting it to work was nontrivial and required grabbing the dlls from an actual Windows 7 installation. So I am looking forward to this work being complete.

Mostly though, I'll hope that developers using Unity will export their games for Linux as well :-).

The Wine github page often gets commits related to mf and mfplat.

I tried to install mfplat for Darksiders Warmestered Edition and it works great!

Good to see them working on getting Wolcen to run. That was one of the last games I backed on Kickstarter, under the promise that it will have a Linux version.

/sarcasm

I wonder why I even care if WINE can run it, since it got promised a Linux version!

Could I ask you exactly what setup you are using? I have tried to get it to run using wine-staging (just tried 5.5, clean wineprefix with DXVK 1.5.5), and it runs horribly slow on my system:

@anarus, it recently works stable and enough fast on my old computer:
Ubuntu 19.10 64 bits - NVIDIA GeForce GTX 770 - Nvidia drivers 435.21 - 1920x1080 - Processor Intel i5-3570 3,4 Ghz - 16 Go RAM - resolution: 1920x1080 - fps: 60 (limited by my tv)

Spoiler, click me

I saw you are using DXVK 1.5.5, you should try 1.6, there is a performance boost for this game in this more recent version.

I wrote a Lutris script for the GOG edition, you could test it here:

This release fixes the intro video in Grim Dawn where it was playing only the first frame and had to be skipped.

Thanks you very much for the suggestions! Unfortunately DXVK 1.6 did not change anything the slightest. I tried your Lutris script but it failed after downloading the installer from GOG. However when I installed it on my laptop (Ryzen 3500U, identical software setup), I got 40FPS so the game might just dislike my hardware.

. I tried your Lutris script but it failed after downloading the installer from GOG

GOG recently changed their API and Lutris does no more know how to download automatically GOG setup files.
Workaround: use last git version or disconnect GOG sync in "import games..." menu. Then Lutris will no more automatically download GOG setup file and will ask you instead for a local setup file.

However when I installed it on my laptop (Ryzen 3500U, identical software setup), I got 40FPS so the game might just dislike my hardware.

I think you found the cause.
