La ressource Phoronix a publi\u00e9 les r\u00e9sultats d'une comparaison des performances des applications de jeu fonctionnant dans des environnements bas\u00e9s sur Wayland et X.org sous Ubuntu 21.10, sur un syst\u00e8me \u00e9quip\u00e9 d'une carte graphique AMD Radeon RX 6800. Les jeux soumis \u00e0 test incluent Total War: Three Kingdoms, Shadow of the Tomb Raider, HITMAN 2, Xonotic, Strange Brigade, Left 4 Dead 2, Batman: Arkham Knight, Counter-Strike: Global Offensive et F1 2020. Les tests ont \u00e9t\u00e9 r\u00e9alis\u00e9s \u00e0 des r\u00e9solutions d'\u00e9cran de 3840\u00d72160 et 1920\u00d71080, tant pour les versions Linux natives des jeux que pour les jeux Windows ex\u00e9cut\u00e9s via Proton + DXVK. <\/p>\n

En moyenne, les jeux dans une session GNOME bas\u00e9e sur Wayland ont affich\u00e9 un FPS sup\u00e9rieur de 4 % par rapport \u00e0 une session GNOME sous X.org. Dans la plupart des tests, KDE 5.22.5 \u00e9tait l\u00e9g\u00e8rement \u00e0 la tra\u00eene par rapport \u00e0 GNOME 40.5 lors de l'utilisation de Wayland, mais a surpass\u00e9 GNOME lors de l'utilisation de X.Org dans les tests de la plupart des jeux (Counter-Strike: Global Offensive, F1 2020, Shadow of the Tomb Raider, Left 4 Dead 2, Xonotic, Total War: Three Kingdoms, Strange Brigade).

\"Comparaison<\/center> <\/p>\n

Pour les jeux \u00ab Total War: Three Kingdoms \u00bb et \u00ab Shadow of the Tomb Raider \u00bb, il n'a pas \u00e9t\u00e9 possible d'effectuer les tests KDE bas\u00e9s sur Wayland en raison de plantages des jeux. Dans HITMAN 2, en utilisant KDE, quel que soit le sous-syst\u00e8me graphique, un retard anormal de plus de deux fois par rapport \u00e0 GNOME et Xfce a \u00e9t\u00e9 observ\u00e9.

\"Comparaison<\/center> <\/p>\n

Xfce a \u00e9t\u00e9 test\u00e9 uniquement avec X.org et, dans la plupart des mesures, se trouvait en derni\u00e8re position, except\u00e9 lors des tests du jeu Strange Brigade \u00e0 la r\u00e9solution 1920\u00d71080, o\u00f9 Xfce a pris la premi\u00e8re place, tant pour les versions natives du jeu que pour l'utilisation de la couche Proton. Cependant, dans le test \u00e0 la r\u00e9solution 3840\u00d72160, Xfce \u00e9tait en derni\u00e8re position. Ce test a \u00e9galement \u00e9t\u00e9 remarquable en ce sens que la session Wayland de KDE a devanc\u00e9 GNOME.

\"Comparaison<\/center> <\/p>\n

Dans les jeux prenant en charge OpenGL et Vulkan, l'utilisation de Vulkan a conduit \u00e0 un FPS environ 15 % plus \u00e9lev\u00e9.

\"Comparaison<\/center> <\/p>\n

De plus, des r\u00e9sultats de comparaison des performances de divers jeux et applications de test utilisant les noyaux Linux 5.15.10 et 5.16-rc sur des ordinateurs portables avec des processeurs Ryzen 7 PRO 5850U et Ryzen 5 5500U ont \u00e9t\u00e9 publi\u00e9s. Les tests ont montr\u00e9 une augmentation significative des performances (de 2 \u00e0 14 %) lors de l'utilisation du noyau Linux 5.16, qui demeure ind\u00e9pendante de la version de Mesa (la branche 22.0-dev a \u00e9t\u00e9 utilis\u00e9e lors du test final). La sortie du noyau 5.16 est attendue pour le 10 janvier. Il n'est pas encore clair quel changement dans le noyau 5.16 a entra\u00een\u00e9 l'augmentation des performances, mais il est suppos\u00e9 qu'il s'agit d'une combinaison d'am\u00e9liorations li\u00e9es \u00e0 l'utilisation du CPU dans le planificateur de t\u00e2ches et d'optimisations li\u00e9es \u00e0 la prise en charge des GPU Radeon Vega dans le pilote AMDGPU.

\"Comparaison<\/center> <\/p>\n

De plus, il convient de noter la sortie du pilote graphique AMDVLK, qui fournit une impl\u00e9mentation de l'API graphique Vulkan, d\u00e9velopp\u00e9e par AMD. Avant l'ouverture du code, le pilote \u00e9tait inclus dans l'ensemble de pilotes propri\u00e9taires AMDGPU-PRO et \u00e9tait en concurrence avec le pilote Vulkan open source RADV, d\u00e9velopp\u00e9 par le projet Mesa. Depuis 2017, le code du pilote AMDVLK est ouvert sous la licence MIT. La nouvelle version se distingue par son support de la sp\u00e9cification Vulkan 1.2.201, la mise en \u0153uvre de l'extension Vulkan VK_EXT_global_priority_query et la r\u00e9solution de probl\u00e8mes de performance dans des environnements bas\u00e9s sur Wayland (dans Ubuntu 21.04, une session bas\u00e9e sur Wayland a montr\u00e9 une baisse de performance de 40% par rapport \u00e0 Ubuntu 20.04 avec une session X.Org).
