Tests ran on an RTX 5070 with the R610 driver branch across KDE KWin 6.7.4, GNOME Mutter 49.7, and X.Org Server 1.21.1.24. Results show latency between the two is very close with no clear winner, XWayland no longer adds the extra frame delay it used to, and Variable Refresh Rate drastically improves responsiveness with similar latency on both. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does XWayland still add extra frame latency compared to native X.Org or Wayland? No, XWayland no longer introduces the extra frame delay it used to in past testing. NVIDIA's scientific latency comparison, presented at XDC 2026 using a micro-controller and light sensor for precise end-to-end measurement, found this regression resolved when testing on an RTX 5070 with the R610 driver branch, KDE KWin 6.7.4, and GNOME Mutter 49.7. _Track how XWayland and compositor latency evolve as Linux desktop stacks mature on daily.dev._ ### Is Wayland or X.Org faster in terms of input latency on NVIDIA GPUs? Neither is clearly faster; NVIDIA's testing found latency results between X.Org and Wayland are very close, making it hard to declare a winner. Measurements used an RTX 5070, the R610 driver branch, X.Org Server 1.21.1.24, KDE KWin 6.7.4, and GNOME Mutter 49.7, with a micro-controller and light sensor for accuracy. _Developers weighing X.Org versus Wayland for latency-sensitive setups can follow findings like this on daily.dev._ ### Does enabling Variable Refresh Rate (VRR) reduce latency on Wayland and X.Org? Yes, VRR was measured to drastically improve responsiveness and delivered roughly the same latency whether running X.Org or Wayland sessions, based on NVIDIA's testing with an RTX 5070 and R610 driver branch presented at XDC 2026. _Anyone tuning display latency with VRR can keep up with graphics stack benchmarks on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@akkitto** · 1 upvotes > Wayland is best. ## Similar posts on daily.dev -
