From the sticky:

  quot;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".

  官方論壇的置頂帖子。

  翻譯大概就是，打開選項->選擇 graphic options menu-> 把 'Post Processing' 的選擇去掉 就可以了。

  這個應該是游戲本身的問題，和破解 顯卡關系都不大
