Kamil \u0141ysik, che lavora per NVIDIA, ha parlato alla conferenza XDC 2026 presentando i risultati dei test sui ritardi nell'output delle informazioni negli ambienti GNOME 49.7 (mutter) e KDE 6.7.4 (kwin) utilizzando X.Org Server e Wayland. Il codice utilizzato nella ricerca \u00e8 stato pubblicato con licenza MIT. <\/p>\n

In generale, le conclusioni indicano che le differenze nella reattivit\u00e0 non sono significative e \u00e8 difficile identificare un vincitore. Secondo Kamil, i ritardi sono maggiormente influenzati dalla gestione degli input e dall'organizzazione dell'output sul monitor. \u00c8 stata menzionata in particolare la tecnologia di variazione adattiva della frequenza di aggiornamento dello schermo (VRR), il cui attivamento ha notevolmente aumentato la reattivit\u00e0. Sono inoltre state segnalate soluzioni per i problemi di ritardo riscontrati nei test precedenti con XWayland \u2014 nella nuova base di codice di XWayland non sono stati registrati ritardi aggiuntivi. <\/p>\n

Il metodo proposto per valutare la reattivit\u00e0 dell'interfaccia \u00e8 simile a uno studio condotto a luglio da Mark Nett. Come nello studio precedente, per misurare con precisione il tempo dal momento in cui si preme un tasto fino al cambiamento delle informazioni sullo schermo \u00e8 stato utilizzato un dispositivo hardware speciale basato su un microcontrollore ESP32-S3, al quale \u00e8 stato collegato un fotodiodo per rilevare il cambiamento della luminosit\u00e0 di un punto sullo schermo, simulando l'uso di una tastiera USB. Per l'uscita sono state impiegate una scheda grafica NVIDIA GeForce RTX 5070 e un monitor LG 27GN950. Il sistema utilizzava il kernel Linux 7.1.7 e un insieme di driver proprietari NVIDIA 610.57.04.
