我正在开发一款小型卡片交换世界旅行游戏，我将其设想为 gem 迷阵和 10 天地理棋盘游戏的混合体。到目前为止，编码一直没问题，但帧率非常糟糕……目前我的 Core 2 Duo 的帧率已经降到 20 多岁了。这是一个问题，因为我正在为英特尔 3 月的开发者竞赛创建游戏，该竞赛直接针对搭载动力不足的 Atom 处理器的上网本。
这是游戏的屏幕:

我是 Python 和 Pygame 的新手(这是我第一次使用它们)，遗憾的是我缺乏正式的 CS 培训......也就是说我认为可能有很多不好的地方在我的代码中进行的实践，还有很多可以优化的地方。如果你们中的一些 Python 老手不介意看一下我的代码，看看您是否找不到任何明显的优化区域，我将非常感激。
您可以在此处下载完整源代码(Python 2.6 + Pygame 1.9): http://www.necessarygames.com/my_games/betraveled/betraveled_src0328.zip
编译后的 exe 在这里: www.necessarygames.com/my_games/betraveled/betraveled_src0328.zip
我担心的一件事是我的事件管理器，我觉得它可能有一些性能整体，另一件事是我的渲染......我几乎只是一直把所有东西都发送到屏幕上(见下面我的 game_components.py 中的渲染例程)；我最近发现您应该只更新屏幕上发生变化的区域，但我仍然不清楚这是如何实现的……这会不会是一个巨大的性能问题？
非常感谢任何想法! 像往常一样，我很乐意通过 PayPal“打赏”您的时间和精力。

多亏了下面的建议，我对我的代码运行了 cprofile。如果有人愿意查看此输出并让我知道什么是预期的和什么不是预期的，那就太好了。
这是 p.strip_dirs().sort_stats('cumulative').print_stats() 的输出:

最佳答案
让事件通过 event.wait 来找你
您真的需要在每次报价时都进行处理吗？如果不是，请使用 pygame.event.wait让你的事件循环只在事件进入时处理，并且pygame.time.set_timer如果您需要像 SecondEvent 这样的周期性事件.
这意味着您不会在没有事件进入的几秒钟内绘制很多帧，但这没关系。使用 event.wait 会降低 CPU 使用率并让您仍然保持响应，并且可能会消除对 time.wait 的需求。
不要每次都从头开始重新绘制整个棋盘
不要让 Room.render 每次都 blit 背景，这意味着它必须重新绘制整个棋盘和所有卡片。这样做一次。然后不要让卡片重新渲染自己，除非它们改变了黑暗或正在移动。
当牌在移动时，您应该能够通过只传送背景图形的一部分而不是整个图形来恢复背景。
将矩形列表传递给 display.update
一旦您只更新某些区域，您可以将这些区域传递给 display.update所以它不必更新整个屏幕。例如，see the Solarwolf code以及它如何标记脏矩形。
