Kamil \u0141ysik, kt\u00f3ry pracuje w firmie NVIDIA, wyst\u0105pi\u0142 na konferencji XDC 2026 z prezentacj\u0105, w kt\u00f3rej przedstawi\u0142 wyniki test\u00f3w op\u00f3\u017anie\u0144 wyj\u015bcia informacji w \u015brodowiskach GNOME 49.7 (mutter) i KDE 6.7.4 (kwin) przy u\u017cyciu X.Org Server i Wayland. Kod u\u017cyty w badaniu zosta\u0142 opublikowany na licencji MIT. <\/p>\n

Og\u00f3lnie wnioski sprowadzaj\u0105 si\u0119 do tego, \u017ce r\u00f3\u017cnice w responsywno\u015bci s\u0105 niewielkie i trudno wskaza\u0107 jednego zwyci\u0119zc\u0119.

Proponowana metoda oceny responsywno\u015bci interfejsu jest zbli\u017cona do badania przeprowadzonego w lipcu przez Marka Netta. Podobnie jak w poprzednim badaniu, do dok\u0142adnego pomiaru czasu od naci\u015bni\u0119cia klawisza do zmiany informacji na ekranie u\u017cyto specjalnego urz\u0105dzenia sprz\u0119towego opartego na mikrokontrolerze ESP32-S3, do kt\u00f3rego pod\u0142\u0105czono fotodiod\u0119 w celu rejestracji zmiany jasno\u015bci punktu na ekranie, a tak\u017ce zapewniono symulacj\u0119 pracy klawiatury USB. Do wy\u015bwietlania wykorzystano kart\u0119 graficzn\u0105 NVIDIA GeForce RTX 5070 oraz monitor LG 27GN950. W systemie zastosowano j\u0105dro Linux 7.1.7 oraz zestaw w\u0142asno\u015bciowych sterownik\u00f3w NVIDIA 610.57.04.
