All of a sudden, the game didn't hang...that is, not before I had watched the intro and taken a few steps in the jail where the story starts. It seems the problem is the same as what others have been complaining about here, namely sluggish performance. The interesting part is that my laptop does not support multithreading so I cannot remedy the problem just by turning off extra cores/threads. Also, the game ran just fine in windowed mode, with nearly all graphical extras turned on.
The problem, on my old laptop at least, appears to boil down to the game's sudden need for extra computing power. I had a perfomance monitoring program on while playing just to see whether there would be any dramatic changes, and it turned out the 'crash' is actually the result of my computer running out of resources - processor usage went up from little under 40% to full 100% in a split second. This would also happen before I even got through the start menu. To make a long story short, my laptop is powerful enough to run Enclave easily except when the program goes crazy, but I have no means of fixing this.
