关于城镇界面卡死的真正原因及解决方案

supeipei307

相信很多朋友都发现在升级了nVidia的驱动后，进入城镇界面时很容易就卡死了，表现为游戏画面停止但是音乐仍然在播放，切换回桌面打开任务管理器却显示程序正在运行而不是失去响应。

这个问题在育碧的官方论坛都已经炸开花了，终于有人发布了关于造成这个原因的说明，链接如下：

全文及大意如下：
Hello guys,

there are some good news about Nvidia issue.
我有些关于nVidia驱动引起的问题的好消息

Back in July 2012, when the revamped townscreens were introduced, the dev team used a specific rendering method to support pixel-precise selection of the buildings.
去年七月份加入城镇界面后，开发组用了一个特殊的透视图（rendering，不知道是不是这个意思）方法（也就是函数，下同）来支持建筑物的pixel-precise selection（不懂啥意思）效果

This method at the time worked just fine with the current Nvidia drivers’ version. No related crash was detected, neither by our tests or the community, since the method was supported.
这个方法在那时候的nVidia驱动下是OK的， 无论是我们自己还是社区的测试都没有发现游戏崩溃的现象，因为当时的驱动是支持这个方法的。

In October 2012 Nvidia released a new version of drivers that changed the support of a few methods for some Nvidia devices, leading to the so-called Town Screen crash.
到去年十月份，nVidia发布了新的驱动，里面变更了一些设备的一些方法，导致了这个所谓的城镇界面崩溃问题。

This affected several other games across the board, not only Heroes VI. The issue was difficult to pin-point as it had a quite unpredictable reproduction step and unreliable reproduction rate.
这不仅影响到了英雄无敌六，也影响到了一些别的游戏，并且这个问题很难被定位因为它非常难以被重现（就是不是很稳定的出现，不知道什么情况下一定会出现）。

For many months the M&M team has investigated hand in hand with Nvidia teams, until we came to a breakthrough two weeks ago. We have now fixed our rendering method and so far the fix seems to be rock solid. We still have some tests to run on our end and we hope to be able to release the 2.0 patch beg of April.
几个月来，英雄无敌的开发团队联合nVidia团队一起调查了这个问题，直到两周前我们取得了一个突破性的进展。我们已经修正了我们的透视图方法而且到目前为止这个修正看上去是非常可靠的。我们仍在有一些测试需要完成，然后我们希望可以在4月份发布解决这个问题的2.0补丁。

We apologize for the time it took to find and fix this issue, and we really hope you will be able to enjoy once again Heroes the way it should be. In the meantime, please roll back to Nvidia drivers 301.42 until the release of the patch.
我们对于花了这么久才找到并解决问题感到非常抱歉，我们非常希望能尽快使您能再一次畅玩英雄无敌六。在此期间（补丁尚未发布之前），请回滚您的nVidia驱动版本至301.42。

所以桶子们，解决这个问题的方法目前只有一个就是回滚驱动，或者说叫降低驱动版本，然后坐等2.0的补丁发布就好了。
