Ressourcen Phoronix har offentliggjort resultaterne af en sammenligning af ydeevnen af spilapplikationer, der k\u00f8res i milj\u00f8er baseret p\u00e5 Wayland og X.org i Ubuntu 21.10 p\u00e5 et system med grafikkortet AMD Radeon RX 6800. Testningen omfattede spillene 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 og F1 2020. Testene blev udf\u00f8rt ved sk\u00e6rmopl\u00f8sningerne 3840\u00d72160 og 1920\u00d71080 b\u00e5de for de native Linux-versioner af spillene og for Windows-spillene, der blev k\u00f8rt med brug af kombinationen Proton + DXVK. <\/p>\n

I gennemsnit viste spil i GNOME-sessionen baseret p\u00e5 Wayland en FPS, der var 4% h\u00f8jere end i sessionen GNOME oven p\u00e5 X.org. I de fleste tests var KDE 5.22.5 en smule bagud sammenlignet med GNOME 40.5 ved brug af Wayland, men overgik det ved brug af X.org i testene af de fleste spil (Counter-Strike: Global Offensive, F1 2020, Shadow of the Tomb Raider, Left 4 Dead 2, Xonotic, Total War: Three Kingdoms, Strange Brigade).

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

For spillene \u00abTotal War: Three Kingdoms\u00bb og \u00abShadow of the Tomb Raider\u00bb var det ikke muligt at gennemf\u00f8re KDE-tests baseret p\u00e5 Wayland p\u00e5 grund af nedbrud af spillene. I spillet HITMAN 2, ved brug af KDE, uanset den grafiske subsystem, blev der observeret en unormal mere end to gange forskydning fra GNOME og Xfce.

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

Xfce blev kun testet med X.org og l\u00e5 i de fleste m\u00e5linger sidst, undtagen i testene af spillet Strange Brigade ved opl\u00f8sningen 1920\u00d71080, hvor Xfce rykkede op p\u00e5 f\u00f8rstepladsen b\u00e5de ved k\u00f8rsel af de native versioner af spillet og ved brug af lagdelingen Proton. I testen med opl\u00f8sningen 3840\u00d72160 blev Xfce dog sidst. Denne test var ogs\u00e5 bem\u00e6rkelsesv\u00e6rdig, da Wayland-sessionen KDE slog GNOME.

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

I spil, der underst\u00f8tter OpenGL og Vulkan, var FPS ved brug af Vulkan cirka 15% h\u00f8jere.

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

Derudover er der offentliggjort resultater af ydeevne sammenligning af forskellige spil og testapplikationer ved brug af Linux-kernene 5.15.10 og 5.16-rc p\u00e5 b\u00e6rbare computere med Ryzen 7 PRO 5850U og Ryzen 5 5500U-processorer. Testene viste en m\u00e6rkbar stigning i ydeevnen (fra 2 til 14%) ved brug af Linux-kernen 5.16, som forbliver uafh\u00e6ngig af Mesa-versionen (den endelige test brugte 22.0-dev-grenen). Udgivelsen af kernen 5.16 forventes den 10. januar. Det er ikke helt klart, hvilken \u00e6ndring i kernen 5.16 der f\u00f8rte til ydeevneforbedringen, men det antages, at det er en kombination af forbedringer relateret til brugen af CPU i opgaveplanl\u00e6ggeren og optimeringer til underst\u00f8ttelse af GPU Radeon Vega i AMDGPU-driveren.

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

Derudover kan det bem\u00e6rkes, at grafikkdriveren AMDVLK er udgivet, hvilket giver en implementering af det grafiske API Vulkan, udviklet af AMD. Indtil koden blev \u00e5bnet, blev driveren leveret som en del af den propriet\u00e6re AMDGPU-PRO-driverpakke og konkurrerede med den \u00e5bne Vulkan-driver RADV, der er udviklet af Mesa-projektet. Siden 2017 har AMDVLK-driverens kode v\u00e6ret \u00e5bent under MIT-licensen. Den nye udgave er bem\u00e6rkelsesv\u00e6rdig for sin st\u00f8tte til Vulkan-specifikationen 1.2.201, implementeringen af Vulkan-udvidelsen VK_EXT_global_priority_query og l\u00f8ser ydeevneproblemer i Wayland-baserede milj\u00f8er (i Ubuntu 21.04 med Wayland-session blev der observeret et fald i ydeevnen p\u00e5 40% i forhold til Ubuntu 20.04 med X.Org-session).
