Editing Wine (software) (section)

====Direct3D====
Much of Wine's DirectX effort goes into building WineD3D, a translation layer from Direct3D and [[DirectDraw]] API calls into [[OpenGL]]. As of 2019, this component supports up to DirectX 11.<ref name="wine-40"/> As of 12 December 2016, Wine is good enough to run ''[[Overwatch (video game)|Overwatch]]'' with D3D11.<ref>{{cite web |url=http://www.phoronix.com/scan.php?page=news_item&px=Wine-Patches-Overwatch-Working |title=With Wine Git, You Can Run The D3D11 Blizzard Overwatch Game on Linux |publisher=Phoronix |date=12 December 2016 |access-date=17 December 2016 |archive-date=15 December 2016 |archive-url=https://web.archive.org/web/20161215120551/http://phoronix.com/scan.php?page=news_item&px=Wine-Patches-Overwatch-Working |url-status=live }}</ref> Besides being used in Wine, WineD3D DLLs have also been used on Windows itself, allowing for older GPUs to run games using newer DirectX versions and for old DDraw-based games to render correctly.<ref>{{cite web |last1=Dossena |first1=Federico |title=WineD3D For Windows |url=https://fdossena.com/?p=wined3d%2Findex.frag |website=Federico Dossena |access-date=22 April 2019 |archive-date=13 June 2019 |archive-url=https://web.archive.org/web/20190613212938/https://fdossena.com/?p=wined3d%2Findex.frag |url-status=live }}</ref>

Some work is ongoing to move the Direct3D backend to Vulkan API. Direct3D 12 support in 4.0 is provided by a "vkd3d" subproject,<ref name="wine-40"/> and WineD3D has in 2019 been experimentally ported to use the Vulkan API.<ref name="wine-46">{{cite web |title=Wine 4.6 |url=https://www.winehq.org//announce/4.6 |website=WineHQ |access-date=22 April 2019 |language=en |archive-date=13 April 2019 |archive-url=https://web.archive.org/web/20190413105408/https://www.winehq.org/announce/4.6 |url-status=live }}</ref> Another implementation, [[DXVK]], translates Direct3D 8, 9, 10, and 11 calls using Vulkan as well and is a separate project.<ref>{{Citation|last=Rebohle|first=Philip|title=doitsujin/dxvk|date=4 May 2021|url=https://github.com/doitsujin/dxvk|access-date=4 May 2021|archive-date=26 May 2020|archive-url=https://web.archive.org/web/20200526133505/https://github.com/doitsujin/dxvk|url-status=live}}</ref>

Wine, when patched, can alternatively run Direct3D 9 API commands directly via a [[Free and open-source software|free and open-source]] [[Gallium3D]] State Tracker (aka Gallium3D GPU driver) without translation into OpenGL API calls. In this case, the Gallium3D layer allows a direct pass-through of DX9 drawing commands which results in performance improvements of up to a factor of 2.<ref name="d3d9">{{cite web |url=https://lists.freedesktop.org/archives/mesa-dev/2013-July/041900.html |title=Direct3D 9 Gallium3D State Tracker |author=Christoph Bumiller |date=16 July 2013 |quote=there are a couple of differences to d3d1x: ''[...]'' it's written in C instead of C++ and not relying on horrific multiple inheritance with ''[...]'' So far I've tried Skyrim, Civilization 5, Anno 1404 and StarCraft 2 on the nvc0 and r600g drivers, which work pretty well, at up to x2 the fps I get with wined3d (Note: no thorough benchmarking done yet). |access-date=10 January 2021 |archive-date=27 January 2021 |archive-url=https://web.archive.org/web/20210127092353/https://lists.freedesktop.org/archives/mesa-dev/2013-July/041900.html |url-status=live }}</ref> As of 2020, the project is named Gallium.Nine. It is available now as a separate standalone package and no longer needs a patched Wine version.<ref name="Gallium.Nine">{{cite web |title=Gallium Nine Standalone |url=https://github.com/iXit/wine-nine-standalone |website=github |access-date=3 December 2020 |language=en |archive-date=12 November 2020 |archive-url=https://web.archive.org/web/20201112032739/https://github.com/iXit/wine-nine-standalone |url-status=live }}</ref>
