阿玛拉王国的黑屏情况属于游戏本身的制作问题，跟玩家的显卡以及机器配置无关，官方已经给出了最新的解决黑屏的方法，大家可以参考。

If you're playing the Reckoning demo on the PC and are experiencing a black screen after the cinematics play, please try going into your graphic options menu in the demo and set "Post Processing" to off. We apologize for this issue; it has since been fixed in the final version of Reckoning". 

大致意思就是：打开选项->选择 graphic options menu-> 把 'Post Processing' 的选择去掉
