DXVK as default wined3d backend on VK capable hardware

Summary

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

Current status

• Targeted release: Fedora 33

• FESCo issue: <will be assigned by the Wrangler>
• Tracker bug: <will be assigned by the Wrangler>
• Release notes tracker: <will be assigned by the Wrangler>

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.

DXVK relies on Vulkan support on GPU. More detailed description is available on DXVK Github page ( https://github.com/doitsujin/dxvk ).

DXVK is available to users as 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, PR ( https://src.fedoraproject.org/rpms/wine-dxvk/pull-request/4# ) will be merged into 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 wine package itself.

Benefit to Fedora

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 and users had to know about this project and install it manually (or use eg. Lutris). Having DXVK included by default will make sure everybody gets the best possible performance and compatibility.
