Kamil \u0141ysik, qui travaille pour NVIDIA, a pris la parole lors de la conf\u00e9rence XDC 2026 avec une pr\u00e9sentation sur les r\u00e9sultats des tests de latence de sortie d'informations dans les environnements GNOME 49.7 (mutter) et KDE 6.7.4 (kwin) en utilisant X.Org Server et Wayland. Le code utilis\u00e9 dans l'\u00e9tude a \u00e9t\u00e9 publi\u00e9 sous la licence MIT. <\/p>\n

Dans l'ensemble, les conclusions montrent que les diff\u00e9rences de r\u00e9activit\u00e9 ne sont pas significatives et qu'il est difficile de d\u00e9signer un gagnant. Selon Kamil, la plus grande influence sur les latences provient du traitement des entr\u00e9es et de l'organisation de la sortie vers le moniteur. La technologie de changement adaptatif de la fr\u00e9quence de rafra\u00eechissement (VRR) a \u00e9t\u00e9 mise en avant, son activation ayant permis une am\u00e9lioration notable de la r\u00e9activit\u00e9. De plus, il a \u00e9t\u00e9 mentionn\u00e9 que les probl\u00e8mes de latence, auparavant observ\u00e9s lors des tests utilisant XWayland, ne se sont pas manifest\u00e9s dans la nouvelle base de code de XWayland. <\/p>\n

La m\u00e9thode d'\u00e9valuation de la r\u00e9activit\u00e9 de l'interface propos\u00e9e est semblable \u00e0 celle d'une \u00e9tude r\u00e9alis\u00e9e en juillet par Mark Nett. Comme dans l'\u00e9tude pr\u00e9c\u00e9dente, un mat\u00e9riel sp\u00e9cialis\u00e9 bas\u00e9 sur le microcontr\u00f4leur ESP32-S3 a \u00e9t\u00e9 utilis\u00e9 pour mesurer avec pr\u00e9cision le temps entre l'appui sur une touche et le changement d'information \u00e0 l'\u00e9cran. Un photodiode \u00e9tait connect\u00e9e pour d\u00e9tecter le changement de luminosit\u00e9 d'un pixel \u00e0 l'\u00e9cran, et une simulation d'un clavier USB a \u00e9t\u00e9 mise en place. Une carte graphique NVIDIA GeForce RTX 5070 et un moniteur LG 27GN950 ont \u00e9t\u00e9 utilis\u00e9s pour l'affichage. Le syst\u00e8me fonctionnait avec le noyau Linux 7.1.7 et un ensemble de pilotes propri\u00e9taires NVIDIA 610.57.04.
