Publi\u00e9<\/a><\/noindex> publication de la couche DXVK 1.2<\/a><\/noindex>, fournissant une impl\u00e9mentation de DXGI (DirectX Graphics Infrastructure), de Direct3D 10 et de Direct3D 11, fonctionnant via la traduction des appels vers l'API Vulkan. Pour utiliser DXVK n\u00e9cessite<\/a><\/noindex> des pilotes prenant en charge API Vulkan<\/a><\/noindex>, tels que
\nAMD RADV 18.3, AMDGPU PRO 18.50, NVIDIA 415.22, Intel ANV 19.0 et AMDVLK<\/a><\/noindex>. <\/p>\n

DXVK peut \u00eatre utilis\u00e9 pour ex\u00e9cuter des applications et des jeux 3D sur Linux \u00e0 l'aide de Wine, se pr\u00e9sentant comme une alternative plus performante \u00e0 l'impl\u00e9mentation int\u00e9gr\u00e9e de Wine de Direct3D 11, fonctionnant au-dessus d'OpenGL. Dans certains jeux<\/a><\/noindex> les performances de l'association Wine+DXVK se distingue<\/a><\/noindex> sont inf\u00e9rieures de seulement 10 \u00e0 20 % par rapport \u00e0 un lancement sous Windows, tandis que l'utilisation de l'impl\u00e9mentation Direct3D 11 bas\u00e9e sur OpenGL entra\u00eene une diminution plus significative des performances. <\/p>\n

la nouvelle version, un fil s\u00e9par\u00e9 a \u00e9t\u00e9 d\u00e9di\u00e9 \u00e0 la transmission du tampon de commandes, ce qui a permis d'am\u00e9liorer les performances dans certaines configurations multic\u0153urs. De plus, la fr\u00e9quence d'envoi du tampon de commandes a \u00e9t\u00e9 augment\u00e9e pour \u00e9liminer les temps d'arr\u00eat et utiliser le GPU de mani\u00e8re plus active. Parmi les applications dont les performances ont \u00e9t\u00e9 positivement impact\u00e9es par ces modifications, le jeu Quake Champions est \u00e0 noter.<\/p>\n

La prise en charge des extensions de rendu sp\u00e9cifiques, qui ne sont pas officiellement d\u00e9finies dans la sp\u00e9cification Direct3D 11 et fournies s\u00e9par\u00e9ment par les fabricants via des biblioth\u00e8ques suppl\u00e9mentaires pour Windows, a \u00e9t\u00e9 ajout\u00e9e. Ces extensions sont n\u00e9cessaires pour le fonctionnement du projet exp\u00e9rimental DXVK-AGS<\/a><\/noindex> avec la mise en \u0153uvre des extensions AGS (AMD GPU Services), propos\u00e9es dans AMD AGS SDK<\/a><\/noindex> et permettant d'utiliser certaines optimisations, y compris celles utilis\u00e9es dans les jeux Resident Evil 2 et Devil May Cry 5. <\/p>\n

Parmi les corrections : une l\u00e9g\u00e8re r\u00e9duction de la charge sur le CPU dans certains jeux. R\u00e9solution d'un probl\u00e8me entra\u00eenant l'ajout d'\u00e9l\u00e9ments superflus dans le cache des \u00e9tats et la recompilation de gestionnaires Vulkan identiques. Correction d'un bug causant des plantages ou une utilisation incorrecte de Vulkan lors de l'application de la m\u00e9thode ClearView. La man\u0153uvre de contournement dans NVAPI, utilis\u00e9e pour r\u00e9soudre des probl\u00e8mes dans le jeu Mirror's Edge Catalyst sur des syst\u00e8mes avec GPU NVIDIA, a \u00e9t\u00e9 d\u00e9sactiv\u00e9e.<\/p>\n
