推荐答案
如果你在写非托管code实际上是好，那么你可能可以写一个更快的图形引擎上的DirectX之上。然而，对于业余爱好者，XNA具有性能的大量的，无论是2D和3D游戏的开发。
If you're actually good at writing unmanaged code, then you'll probably be able to write a faster graphics engine on top of DirectX. However, for the hobbyist, XNA has plenty of performance, both for 2D and 3D game development.
在Xbox 360 - 内置的赛车游戏甚至在全高清运行良好。几个在Xbox Live Arcade游戏已经由XNA社区开发。
Here is a good Channel 9 video where they run an XNA-built racing game on Xbox 360. It runs well even at full HD. Several of the XBox Live Arcade games have been developed by the XNA community.
至于C＃的DirectX，我记得，托管DirectX因为它被称为是不再正式支持XNA以来基本上替换它。我可能是错的，它以来我看着它很长一段时间。
As far as C# DirectX, as I recall, Managed DirectX as it was called, is no longer officially supported since XNA basically replaces it. I could be wrong, its been a very long time since I looked at it.
的性能差异是XNA之间忽略不计，因为托管DirectX，在本质上它们是同样的事情; XNA只是有一些便利位，以减少样板code的你需要写的金额。
The performance differences are negligible between XNA and Managed DirectX since, in essence they're the same thing; XNA just has a few convenience bits to reduce the amount of boilerplate code you need to write.
