O recurso Phoronix publicou os resultados de uma compara\u00e7\u00e3o de desempenho de jogos, executados em ambientes baseados em Wayland e X.org no Ubuntu 21.10 em um sistema com a placa gr\u00e1fica AMD Radeon RX 6800. O teste incluiu os jogos 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 e F1 2020. Os testes foram realizados nas resolu\u00e7\u00f5es de tela 3840\u00d72160 e 1920\u00d71080 tanto para as vers\u00f5es nativas Linux dos jogos quanto para os jogos Windows, rodando com o uso da combina\u00e7\u00e3o Proton + DXVK. <\/p>\n

Em m\u00e9dia, os jogos na sess\u00e3o do GNOME baseada em Wayland mostraram um FPS 4% superior ao da sess\u00e3o do GNOME sobre X.org. Na maioria dos testes, o KDE 5.22.5 ficou um pouco atr\u00e1s do GNOME 40.5 ao usar Wayland, mas superou ao usar X.Org em v\u00e1rios jogos (Counter-Strike: Global Offensive, F1 2020, Shadow of the Tomb Raider, Left 4 Dead 2, Xonotic, Total War: Three Kingdoms, Strange Brigade).

\"Compara\u00e7\u00e3o<\/center> <\/p>\n

Para os jogos \u00abTotal War: Three Kingdoms\u00bb e \u00abShadow of the Tomb Raider\u00bb, n\u00e3o foi poss\u00edvel realizar os testes do KDE com base em Wayland devido a encerramentos inesperados dos jogos. No jogo HITMAN 2, ao usar o KDE, independentemente do subsistema gr\u00e1fico, foi observada uma anomalia de mais de duas vezes o atraso em rela\u00e7\u00e3o ao GNOME e Xfce.

\"Compara\u00e7\u00e3o<\/center> <\/p>\n

O Xfce foi testado apenas com X.org e, na maioria das medi\u00e7\u00f5es, ficou na \u00faltima posi\u00e7\u00e3o, exceto nos testes do jogo Strange Brigade na resolu\u00e7\u00e3o 1920\u00d71080, onde o Xfce se destacou em primeiro lugar tanto nas vers\u00f5es nativas do jogo quanto ao usar a camada Proton. No entanto, no teste com a resolu\u00e7\u00e3o 3840\u00d72160, o Xfce ficou em \u00faltimo lugar. Este teste tamb\u00e9m se destacou pelo fato de que a sess\u00e3o do KDE em Wayland superou o GNOME.

\"Compara\u00e7\u00e3o<\/center> <\/p>\n

Em jogos que suportam OpenGL e Vulkan, ao usar Vulkan, o FPS foi aproximadamente 15% maior.

\"Compara\u00e7\u00e3o<\/center> <\/p>\n

Al\u00e9m disso, foram publicados os resultados da compara\u00e7\u00e3o de desempenho entre v\u00e1rios jogos e aplica\u00e7\u00f5es de teste usando os n\u00facleos Linux 5.15.10 e 5.16-rc em laptops com processadores Ryzen 7 PRO 5850U e Ryzen 5 5500U. Os testes mostraram um aumento significativo de desempenho (de 2 a 14%) ao usar o n\u00facleo Linux 5.16, que se manteve independente da vers\u00e3o do Mesa (no teste final, foi usada a vers\u00e3o 22.0-dev). O lan\u00e7amento do n\u00facleo 5.16 \u00e9 esperado para 10 de janeiro. Qual mudan\u00e7a espec\u00edfica no n\u00facleo 5.16 levou ao aumento de desempenho n\u00e3o est\u00e1 claro, mas sup\u00f5e-se que seja uma combina\u00e7\u00e3o de melhorias relacionadas ao uso da CPU no agendador de tarefas e otimiza\u00e7\u00f5es no suporte a GPU Radeon Vega no driver AMDGPU.

\"Compara\u00e7\u00e3o<\/center> <\/p>\n

Al\u00e9m disso, vale a pena mencionar o lan\u00e7amento do driver gr\u00e1fico AMDVLK, que fornece uma implementa\u00e7\u00e3o da API gr\u00e1fica Vulkan, desenvolvida pela AMD. Antes da libera\u00e7\u00e3o do c\u00f3digo, o driver fazia parte do conjunto propriet\u00e1rio de drivers AMDGPU-PRO e competia com o driver Vulkan de c\u00f3digo aberto RADV, desenvolvido pelo projeto Mesa. Desde 2017, o c\u00f3digo do driver AMDVLK est\u00e1 dispon\u00edvel sob a licen\u00e7a MIT. O novo lan\u00e7amento \u00e9 not\u00e1vel pelo suporte \u00e0 especifica\u00e7\u00e3o Vulkan 1.2.201, a implementa\u00e7\u00e3o da extens\u00e3o Vulkan VK_EXT_global_priority_query e pela resolu\u00e7\u00e3o de problemas de desempenho em ambientes baseados no Wayland (no Ubuntu 21.04, a sess\u00e3o baseada no Wayland apresentou uma queda de desempenho de 40% em compara\u00e7\u00e3o com o Ubuntu 20.04 com a sess\u00e3o X.Org).
