为什么值得看
作者用光传感器+Arduino自制了一套Linux输入延迟测量系统，首次量化对比了X11/Wayland、VRR、DXVK等配置的真实延迟差异。对折腾过gamemode/gamescope却分不清 placebo 和真优化的Linux玩家和开发者，终于有了一把客观标尺。
编辑判断
Linux游戏优化社区长期被玄学参数困扰，这个项目的价值不在硬件方案本身，而在于建立了可复现的测量基准。作者发现Wayland+VRR组合在某些场景下延迟反而高于X11，这与社区共识相矛盾。
做云游戏、串流或竞技游戏引擎的团队可以直接借鉴这套方法验证自己的帧调度策略，而不是依赖用户主观反馈。项目代码和硬件清单已公开，成本控制在50美元以内。

This is why I read Hacker News. Thank you.
He seems confused at the end why people think wayland is so slow, but don't you think it's because of his xwayland result? People were probably running x11 games on wayland and noticed that significant lag. Just a wild guess. Very nice article, wish people did actual measurements like this more ofte
You can't just test one wayland compositor and talk about the performance of all wayland compositors. They're vastly different, especially when it comes to the extensions to wayland needed to handle input devices (ref: https://wayland.app/protocols/). It's not like how xorg is th
