Kamil \u0141ysik, who works at NVIDIA, presented at the XDC 2026 conference a report detailing the results of testing information output delays in GNOME 49.7 (mutter) and KDE 6.7.4 (kwin) environments using X.Org Server and Wayland. The code used in the study is published under the MIT license. <\/p>\n

Overall, the conclusions indicate that the differences in responsiveness are minor and it's hard to identify a clear winner. According to Kamil, the biggest impact on delays comes from input processing and the way output is organized to the monitor. The technology of adaptive refresh rate (VRR) was specifically noted, as its activation significantly improved responsiveness. Issues with delays noted in previous tests when using XWayland are no longer present in the new XWayland codebase. <\/p>\n

The proposed method for evaluating interface responsiveness is similar to a study conducted by Mark Nett in July. As in the previous study, a specialized hardware device based on the ESP32-S3 microcontroller was used for accurate measurement of the time from keypress to information change on the screen, along with a photodiode to detect brightness changes on the screen, simulating USB keyboard functionality. The NVIDIA GeForce RTX 5070 graphics card and LG 27GN950 monitor were utilized for output. The system used the Linux kernel 7.1.7 along with the proprietary NVIDIA driver set 610.57.04.
