A quick report 
When i was on Vista ultimate 32 bit I had a lot of crashes. Chapter 2 became unplayable even, load times were horrid, and the game just wasnt worth all the bugs i was encountering.So, a friend told me to try 64 bit, so i did...and you know what? NO CRASHES YET!Im on Chapter 3 now and no crashes, no stutter, INSANE loading speeds (1.2 patch), and it runs like a dream!Thankyou 64 bit!
