Kamil \u0141ysik, werkzaam bij NVIDIA, sprak op de XDC 2026-conferentie over de resultaten van het testen van de outputvertragingen in GNOME 49.7 (mutter) en KDE 6.7.4 (kwin) met gebruik van de X.Org Server en Wayland. De code die in het onderzoek is gebruikt, is gepubliceerd onder de MIT-licentie. <\/p>\n

Over het algemeen komen de conclusies erop neer dat de verschillen in responsiviteit niet significant zijn en dat het moeilijk is om een duidelijke winnaar aan te wijzen. Volgens Kamil hebben invoerverwerking en de organisatie van de output naar de monitor de grootste invloed op de vertragingen. De technologie voor adaptieve verversingssnelheid (VRR) werd afzonderlijk vermeld, waarvan de inschakeling de responsiviteit aanzienlijk verbeterde. Ook werd er melding gemaakt van oplossingen voor vertragingen die in eerdere tests optraden bij het gebruik van XWayland - in de nieuwe codebasis van XWayland zijn er geen extra vertragingen vastgesteld. <\/p>\n

De voorgestelde methode voor het evalueren van de responsiviteit van de interface is vergelijkbaar met het onderzoek dat in juli door Mark Netten werd uitgevoerd. Net als in het vorige onderzoek werd een speciaal hardwareapparaat op basis van de microcontroller ESP32-S3 gebruikt voor het nauwkeurig meten van de tijd van het indrukken van een toets tot de verandering van informatie op het scherm. Een fotodiode was aangesloten om de verandering in helderheid van een punt op het scherm vast te leggen, en een simulatie van een USB-toetsenbord was voorzien. Voor de uitvoer werden een NVIDIA GeForce RTX 5070-grafische kaart en een LG 27GN950-monitor gebruikt. In het systeem werd Linux-kernel 7.1.7 en een set propri\u00ebtaire NVIDIA-drivers 610.57.04 toegepast.
