Kamil \u0141ysik, der arbejder hos NVIDIA, pr\u00e6senterede p\u00e5 XDC 2026 konferencen et foredrag, hvor han talte om testresultaterne for latency i GNOME 49.7 (mutter) og KDE 6.7.4 (kwin) ved brug af X.Org Server og Wayland. Koden, der blev anvendt i unders\u00f8gelsen, er offentliggjort under MIT-licensen. <\/p>\n

Generelt viser konklusionerne, at forskellene i reaktivitet ikke er v\u00e6sentlige, og det er sv\u00e6rt at udpege en klar vinder. If\u00f8lge Kamil har inputbehandling og monitorudgang den st\u00f8rste indflydelse p\u00e5 latency. Teknologien til variabel opdateringsfrekvens (VRR) blev fremh\u00e6vet, da dens aktivering markant forbedrede reaktiviteten. Der blev ogs\u00e5 n\u00e6vnt l\u00f8sninger p\u00e5 problemerne med latency, der tidligere opstod ved brug af XWayland - i den nye XWayland kodebase er der ikke registreret yderligere latency. <\/p>\n

Den foresl\u00e5ede metode til evaluering af interface-responsivitet er n\u00e6rt besl\u00e6gtet med en unders\u00f8gelse, der blev udf\u00f8rt i juli af Mark Nett. Ligesom i den tidligere unders\u00f8gelse blev der anvendt en specialiseret hardwareenhed baseret p\u00e5 ESP32-S3 mikrokontrolleren for n\u00f8jagtigt at m\u00e5le tiden fra tastetryk til \u00e6ndring af information p\u00e5 sk\u00e6rmen, hvor en fotodiod blev tilsluttet for at registrere \u00e6ndringen i lysstyrken af en pixel p\u00e5 sk\u00e6rmen, og USB-tastaturens funktion blev simuleret. Der blev anvendt et NVIDIA GeForce RTX 5070 grafikkort og en LG 27GN950 monitor. Systemet k\u00f8rte p\u00e5 et Linux 7.1.7 kerne og et s\u00e6t propriet\u00e6re NVIDIA drivere 610.57.04.
