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。
這個應該是遊戲本身的問題，和破解 顯卡關係都不大
