我正在开发一款小卡片交换世界旅行游戏，我想象它是宝石迷阵和10天地理棋盘游戏之间的交叉。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上的低20分。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，该竞赛正好针对上网本包装动力不足的Atom处理器。
这是游戏中的屏幕：

我是Python和Pygame的新手（这是我第一次使用它们），而且很遗憾缺乏正式的CS训练...也就是说我认为可能有很多不好的在我的代码中进行的实践，以及可以优化的A LOT。如果你们中的一些老Python手不介意看看我的代码，看看你是否找不到任何明显的优化领域，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exe ： www.necessarygames.com/my_games/betraveled/betraveled_src0328.zip
我关心的一件事是我的活动经理，我觉得其中可能有一些性能整体，另一件事是我的渲染...我几乎只是一直在屏幕上显示所有内容（参见我的game_components.py中的渲染例程）;我最近发现你应该只更新屏幕上已经发生变化的区域，但我仍然对如何完成这一点仍然模糊不清......这可能是一个巨大的性能问题吗？
非常感谢任何想法！ 像往常一样，我很高兴通过PayPal为您提供时间和精力。

感谢下面的建议，我在我的代码上运行了cprofile。如果有人愿意看看这个输出并让我知道什么是不可预期的，那将是很好的。

让事件通过event.wait
来找你你真的需要处理每个滴答？如果没有，请使用pygame.event.wait为您的事件循环仅在事件发生时进行处理，并pygame.time.set_timer如果您需要定期事件，例如SecondEvent。
这意味着当事件没有进入时，你不会在几秒钟内画出很多帧，但这没关系。使用event.wait将降低CPU使用率并让您仍然具有响应能力，并且可能会消除对时间的需求。等等。
每次打勾都不要从头开始重新绘制整个电路板
每次都没有Room.render blit背景，这意味着它必须通过并重新绘制整个板和所有卡。这样做一次。然后，除非他们改变黑暗或他们正在移动，否则不要让卡片重新渲染。
当卡片移动时，您应该能够通过blitting背景图形的一部分而不是整个部分来恢复背景。
将矩形列表传递给display.update
只更新某些区域后，您可以将这些区域传递给display.update，这样就无需更新整个屏幕。例如，see the Solarwolf code以及它如何标记脏矩形。
答案 1 :(得分：2)
在您的个人资料结果中：
我最近发现你应该只更新已经改变的屏幕区域，但我仍然对如何完成这一点仍然模糊......这可能是一个巨大的性能问题吗？
是。 display.update和Surface.blit位于个人资料搜索结果的顶部。你做了超过一百万个blits，大约5000个滴答，每个滴答都有200个blits。
此外，您的个人资料结果中的第六位是display.set_caption，我猜这是FPS计数器本身的显示？在157的7秒，这不是你的主要热点，但仍然很有趣。
答案 2 :(得分：0)
我想说5-10ms的简单等待足以严重降低不断重新渲染屏幕的CPU使用率。
