Portal on OSX 慢一半。果轮出来解释一下？

好奇怪他们为什么不在Mac机器上，而是在hackintosh上测试？

Portal is an easy game to run and so we’re largely being academic here,
but the “tax” for Mac OS X is roughly a generation in hardware performance
. For the performance we’re seeing on a GTX 285 under Mac OS X the results
are similar to what we’d see under Windows with something like a 9800GTX.
你看懂文字了？

Mac OS X is not designed to run on this configuration.
To be more scientific, and more convincing, they have to do the same test on
, say, the latest MBP with 320M or 330M graphic cards.
It is possible Mac game performance is worse. But there could be many
reasons for that. But their tests are just not convincing and not done
correctly.

I am gonna say sth. I am not 果轮 but I don't care if you call me that :-)
Machine could play a factor to make "Mac" slow. However, I would attribute
the performance drop largely to the change of 3D api for the new
implementation on Mac. The new implementation is based on OpenGL and it may
take a while for the devs to fine tune performance. (I guess) the
implementation on Windowns/Xbox is based on direct x.

Mac OS X support for OpenGL 3.0 is not even completed yet.
Not sure Portal is based on OpenGL which version.
Supposedly OpenGL 3.0 is much better than earlier version for games and
stuff?

Unlike DirectX, OpenGL is under fast transformation and it is not surprising
that the implementation is even not using latest features of OpenGL
available on OS X.
Definitely OpenGL3.0 will be a magnitude stronger than previous 2.0. The
problem is however if the driver is able to fully support the add-on
features.
Considering the vital role of OpenGL on OSX platform, I believe Apple is
trying their best to support it on Mac - Apple has been aggressively
extending OpenGL for OSX. The problem is if such extra stuff, which
significantly speed up OpenGL'based applications running on Mac, will be
available on Hackintosh, a rip-off missing the optimization specifically for
Apple's hardware.
So I do think the said test is not scientific. Just my cents since I really
don't know how different a hackintosh and a genuine Mac are and how this
will affect running OpenGL applications on top of them.

ogl一般是支持新功能，速度不会有什么提高。 游戏（还有很多其它软件）移植版本通
常需要重新优化，也包括很多计算，这个不光是ogl的问题。这个是老游戏了，开发商不
会下很大力气优化。所以慢一点确实不说明系统效率问题。

最近有比较OpenGL在Mac OS X 10.6.3和Ubuntu下的性能的文章
文章发现10.6.3的OpenGL支持有regression，有些方面性能下降很多，算是bug。
但是通常情况下，Mac OS X和Ubuntu系统性能总体差不多。不同测试，有时这个快一点
，有时那个快一点。
但是游戏在Windows下一直都比Mac和Linux下快。游戏本身针对系统的优化是一方面。
系统本身对游戏性能的重视也是一方面。

游戏这类程序调用系统功能少，而且多数直接用底层。关键还是看本身优化。开发平台
和移植平台的影响更大一些。osx对大型游戏重视程度没有windows高肯定有关，毕竟定
位和市场都不一样。 |
