Resursen Phoronix har publicerat resultatet av en j\u00e4mf\u00f6relse av prestanda f\u00f6r spelapplikationer som k\u00f6rs i milj\u00f6er baserade p\u00e5 Wayland och X.org i Ubuntu 21.10 p\u00e5 ett system med grafikkortet AMD Radeon RX 6800. Testerna omfattade spelen 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 och F1 2020. Tester genomf\u00f6rdes med sk\u00e4rmuppl\u00f6sningarna 3840\u00d72160 och 1920\u00d71080 b\u00e5de f\u00f6r inhemska Linux-versioner av spelen och f\u00f6r Windows-spel som k\u00f6rdes med Proton + DXVK. <\/p>\n

I genomsnitt visade spelen i GNOME-sessionen baserad p\u00e5 Wayland en FPS som var 4% h\u00f6gre \u00e4n i GNOME-sessionen ovanp\u00e5 X.org. I de flesta tester visade KDE 5.22.5 n\u00e5got s\u00e4mre resultat \u00e4n GNOME 40.5 vid anv\u00e4ndning av Wayland, men presterade b\u00e4ttre vid anv\u00e4ndning av X.Org i tester av de flesta spelen (Counter-Strike: Global Offensive, F1 2020, Shadow of the Tomb Raider, Left 4 Dead 2, Xonotic, Total War: Three Kingdoms, Strange Brigade).

\"Prestandaj\u00e4mf\u00f6relse<\/center> <\/p>\n

F\u00f6r spelen \"Total War: Three Kingdoms\" och \"Shadow of the Tomb Raider\" kunde testerna i KDE-baserade Wayland inte genomf\u00f6ras p\u00e5 grund av krascher i spelen. I spelet HITMAN 2, oavsett grafisk underbyggnad, observerades en onaturlig mer \u00e4n dubbel f\u00f6rdr\u00f6jning j\u00e4mf\u00f6rt med GNOME och Xfce.

\"Prestandaj\u00e4mf\u00f6relse<\/center> <\/p>\n

Xfce testades endast med X.org och i de flesta m\u00e4tningar hamnade den sist, med undantag f\u00f6r testerna av spelet Strange Brigade vid uppl\u00f6sning 1920\u00d71080, d\u00e4r Xfce tog f\u00f6rstaplatsen b\u00e5de vid k\u00f6rning av inhemska versioner av spelet och vid anv\u00e4ndning av Proton. Vid testet med uppl\u00f6sning 3840\u00d72160 kom Xfce d\u00e4remot sist. Denna test var ocks\u00e5 anm\u00e4rkningsv\u00e4rd i och med att KDE-sessionen p\u00e5 Wayland \u00f6vertr\u00e4ffade GNOME.

\"Prestandaj\u00e4mf\u00f6relse<\/center> <\/p>\n

I spel som st\u00f6der OpenGL och Vulkan var FPS vid anv\u00e4ndning av Vulkan ungef\u00e4r 15% h\u00f6gre.

\"Prestandaj\u00e4mf\u00f6relse<\/center> <\/p>\n

Dessutom har resultat publicerats av j\u00e4mf\u00f6relser av prestandan hos olika spel och testapplikationer vid anv\u00e4ndning av Linux-k\u00e4rnorna 5.15.10 och 5.16-rc p\u00e5 b\u00e4rbara datorer med processorer som Ryzen 7 PRO 5850U och Ryzen 5 5500U. Tester visade en p\u00e5taglig \u00f6kning av prestandan (fr\u00e5n 2% till 14%) vid anv\u00e4ndning av k\u00e4rnan Linux 5.16, vilket kvarstod oavsett version av Mesa (i det slutliga testet anv\u00e4ndes grenen 22.0-dev). Lanseringen av k\u00e4rnan 5.16 f\u00f6rv\u00e4ntas den 10 januari. Vilken specifik f\u00f6r\u00e4ndring i k\u00e4rnan 5.16 som ledde till prestandah\u00f6jningen \u00e4r fortfarande oklart, man misst\u00e4nker att det \u00e4r en kombination av f\u00f6rb\u00e4ttringar relaterade till anv\u00e4ndning av CPU i uppgiftsschemal\u00e4ggaren och optimeringar av st\u00f6d f\u00f6r GPU Radeon Vega i AMDGPU-drivrutinen.

\"Prestandaj\u00e4mf\u00f6relse<\/center> <\/p>\n

Dessutom kan vi n\u00e4mna sl\u00e4ppet av den grafiska drivrutinen AMDVLK, som tillhandah\u00e5ller en implementation av grafik-API:et Vulkan, utvecklad av AMD. Fram till \u00f6ppnandet av koden levererades drivrutinen som en del av den propriet\u00e4ra drivrutinsupps\u00e4ttningen AMDGPU-PRO och konkurrerade med den \u00f6ppna Vulkan-drivrutinen RADV, utvecklad av projektet Mesa. Sedan 2017 \u00e4r koden f\u00f6r drivrutinen AMDVLK \u00f6ppen under MIT-licensen.
