我最近换用了 Ubuntu，发现有些应用程序存在微小延迟和低帧率。我有 165Hz 显示器，但 Ubuntu 感觉很延迟。我录制了一些慢动作视频。
我希望滞后和微卡顿是可见的。
我有 Nvidia GeForce RTX 2060 Super GPU，我的驱动程序版本是 535.104.05，CUDA 版本是 12.2，安装了 16GB RAM 和 i7-7700K CPU。
Ubuntu 通常不会使用超过 10% 的 CPU 和 20% 的 GPU，但我遇到了这种延迟和微卡顿，这让我的眼睛很痛。
我使用 X11 作为窗口管理器。我尝试过 Wayland，但它更慢

我想让我的 Ubuntu 感觉更流畅，摆脱微延迟。Wayland 中是否有类似三重缓冲的功能？
