from the sticky:
"blank/black screen with the demo? please read!
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".
官方论坛的置顶帖子。
翻译大概就是，打开选项->选择 graphic options menu-> 把 ’post processing’ 的选择去掉 就可以了。
这个应该是游戏本身的问题，和破解 显卡关系都不大
