Most users reported the previous crack for Anno 1404: dawn of discovery makes your game experience really crappy fps.
But no worries, Razor1911 to the rescue!!
Credits goes to the guys at Suprbay, User ‘exe’ for being one of the first few to provide the links, and Escobar for being the original uploader of the crack in this link, which can be downloaded
User comments largely verify that the crack works great and does not cause your game to lag. I myself donnoe, since I haven’t try it out.. HECK I don’t even own the game, yet. 😉
THEREFORE, PLEASE DO NOT ASK ANY QUESTIONS RELATED TO THIS RELEASE HERE, if in doubt, just head over to suprbay and ask your questions there. there are also other mirrors you can try should you not be able to download from the link provided above.
Page #440+ should be where the rls started getting hawt.
Enjoy! And last but not least, IF YOU LIKE THE GAME, BUY IT!
