Proposal to replace default wined3d backend with DXVK, A Vulkan-based translation layer for Direct3D 9/10/11 which allows running 3D applications on Linux using Wine.
 
Currently, wine in Fedora uses wined3d and users can optionally install DXVK (be it wine-dxvk package or by any other means). With this change accepted, wine would use DXVK instead of wined3d on supported GPUs automatically.

<!-- Expand on the summary, if appropriate. A couple sentences suffices to explain the goal, but the more details you can provide the better. -->
DXVK is an alternative to wined3d providing more performant and more compatible way to run Windows applications and games using DirectX 9, 10 and 11.
 
More detailed description is available on [https://github.com/doitsujin/dxvk DXVK Github].
 
DXVK is available as a wine-dxvk package since Fedora 31. wine-dxvk package uses alternatives system for following wine dll files: d3d9, d3d10.dll and d3d11.dll .
 
Should this proposal be accepted, [https://src.fedoraproject.org/rpms/wine-dxvk/pull-request/4# a Pull Request] will be merged into the wine-dxvk package which ensures it gets set as default backend only on systems with Vulkan support. wine-dxvk will then get added as "Recommends: wine-dxvk" into the wine package itself.
 
Users can run 'dnf reinstall wine-dxvk' after changing hardware configuration to get alternatives to use DXVK or wined3d updated.
 
This proposal can be accepted in a "reduced form" of replacing the default wined3d backend only for DirectX 10 and 11 and leaving DirectX 9 to be handled by the current wined3d.

<!-- What is the benefit to the distribution?  Will the software we generate be improved? How will the process of creating Fedora releases be improved?
Fedora users running recent Windows games will get superior performance and compatibility. Steam already leverages DXVK but there are other Game Stores and standalone games which would benefit from DXVK. Users had to know about this project and install it manually (or use e.g. Lutris), whereas having DXVK included by default will make sure everybody gets the best possible performance and compatibility.
 
      Be sure to include the following areas if relevant:
      If this is a major capability update, what has changed?
          For example: This change introduces Python 5 that runs without the Global Interpreter Lock and is fully multithreaded.
      If this is a new functionality, what capabilities does it bring?
          For example: This change allows package upgrades to be performed automatically and rolled-back at will.
      Does this improve some specific package or set of packages?
          For example: This change modifies a package to use a different language stack that reduces install size by removing dependencies.
      Does this improve specific Spins or Editions?
          For example: This change modifies the default install of Fedora Workstation to be more in line with the base install of Fedora Server.
      Does this make the distribution more efficient?
          For example: This change replaces thousands of individual %post scriptlets in packages with one script that runs at the end.
      Is this an improvement to maintainer processes?
          For example: Gating Fedora packages on automatic QA tests will make rawhide more stable and allow changes to be implemented more smoothly.
      Is this an improvement targeted as specific contributors?
          For example: Ensuring that a minimal set of tools required for contribution to Fedora are installed by default eases the onboarding of new contributors.
 
    When a Change has multiple benefits, it's better to list them all.

DXVK as default wined3d backend on VK capable hardware

Summary

Proposal to replace default wined3d backend with DXVK, A Vulkan-based translation layer for Direct3D 9/10/11 which allows running 3D applications on Linux using Wine.

Currently, wine in Fedora uses wined3d and users can optionally install DXVK (be it wine-dxvk package or by any other means). With this change accepted, wine would use DXVK instead of wined3d on supported GPUs automatically.

Detailed Description

DXVK is an alternative to wined3d providing more performant and more compatible way to run Windows applications and games using DirectX 9, 10 and 11.

More detailed description is available on DXVK Github.

DXVK is available as a wine-dxvk package since Fedora 31. wine-dxvk package uses alternatives system for following wine dll files: d3d9, d3d10.dll and d3d11.dll .

Should this proposal be accepted, a Pull Request will be merged into the wine-dxvk package which ensures it gets set as default backend only on systems with Vulkan support. wine-dxvk will then get added as "Recommends: wine-dxvk" into the wine package itself.

Users can run 'dnf reinstall wine-dxvk' after changing hardware configuration to get alternatives to use DXVK or wined3d updated.

This proposal can be accepted in a "reduced form" of replacing the default wined3d backend only for DirectX 10 and 11 and leaving DirectX 9 to be handled by the current wined3d.

Benefit to Fedora

Steam already leverages DXVK but there are other Game Stores and standalone games which would benefit from DXVK. Users had to know about this project and install it manually (or use e.g. Lutris), whereas having DXVK included by default will make sure everybody gets the best possible performance and compatibility.

I haven't done benchmarking per se, there are multiple resources on the Internet comparing DXVK and wined3d. If necessary I will do additional testing on my hardware in the week of July 27th.

Upgrade/compatibility impact

The aim is to convert users with supported Hardware Configuration to DXVK as a part of Fedora 32 > Fedora 33 upgrade. There should not be any breakage since postinst script of wine-dxvk package would verify if the GPU supports Vulkan or not and set alternatives to wined3d or DXVK accordingly.

There is a slight possibility of user experience degradation compared to wined3d on old Intel iGPUs supporting just a subset of Vulkan specification (Ivy Bridge and Haswell generations). I haven't had any opportunity to test DXVK on such hardware, however, if issues are discovered, check for Vulkan from wine-dxvk package PR ( https://src.fedoraproject.org/rpms/wine-dxvk/pull-request/4#_1__26 ) could be improved to block certain GPU vendors/generations/models.

AMD and/or nVidia GPUs should not be affected, they either do not support Vulkan at all, or they support it fully.

On GPUs without Vulkan support, wine-dxvk would remain installed and unused, consuming about 167 MB of HDD space. Users would be able to opt-out from using DXVK by adding 'exclude=wine-dxvk*' into /etc/dnf/dnf.conf and removing wine-dxvk package.

How To Test

1. Make sure you have Vulkan compatible GPU ('vulkaninfo' runs without errors)

2. Install wine-dxvk package

3. Run some Windows game with wine

A testday will take place before Fedora 33 GA to determine and workaround (disable DXVK and fallback to wined3d) issues on potentially broken hardware and GPU drivers.

In cases when something worked before installing wine-dxvk and stopped after (or regressed), bugs should be reported to DXVK Issue Tracker.
