Javais wrote a first comment killer (!) Following a crippling bug that would crash the game consistently to 3% of its progress. Rummaging through the forums, I found that many of users had solved their problem by testing the game files with a built-in Uplay (the button "play" the game has a small arrow on the side. A click on this arrow causes shows a menu that gives access to this function). It turns out that my installation was defective. Uplay the repaired and the bug is gone.
I think in the setup steps is capricious. My PC is brand new and I doubt that it is in the origin of this corruption. Given the number of people impacted by this issue on forums, I suggest you start this test at the end of installation to remove at least a major cause of crash lexécutable "acu.exe".
Otherwise, the game is a true visual revolution. I would quune GTX750TI is the entrance ticket to enjoy the graphics.
