Kamil \u0141ysik, care lucreaz\u0103 la compania NVIDIA, a sus\u021binut o prezentare la conferin\u021ba XDC 2026, \u00een care a vorbit despre rezultatele test\u0103rii laten\u021bei de redare a informa\u021biilor \u00een medii GNOME 49.7 (mutter) \u0219i KDE 6.7.4 (kwin) folosind X.Org Server \u0219i Wayland. Codul folosit \u00een cercetare a fost publicat sub licen\u021ba MIT. <\/p>\n

\u00cen general, concluziile se reduc la faptul c\u0103 diferen\u021bele \u00een reac\u021bie nu sunt semnificative, iar un c\u00e2\u0219tig\u0103tor clar este greu de identificat. Cel mai mare impact asupra laten\u021bei, conform lui Kamil, este adus de procesarea inputului \u0219i organizarea red\u0103rii pe monitor. Tehnologia de adaptare a frecven\u021bei de reac\u021bie a ecranului (VRR) a fost men\u021bionat\u0103 ca av\u00e2nd un impact semnificativ asupra reac\u021biei. De asemenea, au fost abordate problemele legate de laten\u021b\u0103, care ap\u0103reau \u00een test\u0103rile anterioare cu XWayland - \u00een noua baz\u0103 de cod XWayland nu au fost raportate \u00eent\u00e2rzieri suplimentare. <\/p>\n

Metoda propus\u0103 de evaluare a reactivit\u0103\u021bii interfe\u021bei este similar\u0103 cu studiul realizat \u00een iulie de Mark Nettle. Ca \u0219i \u00een studiul anterior, pentru m\u0103surarea precis\u0103 a timpului \u00eentre ap\u0103sarea tastei \u0219i schimbarea informa\u021biei pe ecran a fost utilizat un dispozitiv hardware special bazat pe microcontrolerul ESP32-S3, la care a fost conectat un fotodiod\u0103 pentru a detecta schimbarea luminozit\u0103\u021bii unui punct de pe ecran, \u0219i a fost simulat\u0103 func\u021bionarea unei tastaturi USB. Pentru ie\u0219ire au fost folosite placa grafic\u0103 NVIDIA GeForce RTX 5070 \u0219i monitorul LG 27GN950. Sistemul a utilizat kernel-ul Linux 7.1.7 \u0219i un set de drivere proprietare NVIDIA 610.57.04.
