I just want to throw in my "it worked! Thank Melitele, it worked!" Vista 32, all the Vista patches, Core 2 Duo, Nvidia 8800GTX, 2 gig RAM, and Witcher patch 1.2. The game crashed intermittently during loads/saves or area transitions, probably every 15 to 20 minutes consistently into chapter 3. In chapter 3, I did both the IncreaseUserVa fix (set it to 3072), and I moved my swap file over to another partition. Not only has it completely stopped crashing on me, but patch 1.2 had caused annoying choppiness in Vizima when there were a lot of NPC's around. That, also, was fixed with the IncreaseUserVa + swap file tweaks. The game now runs smooth as butter in every way.I am happy to put up with some bugs for such an awesome game. I am an RPG addict, and this game is pure crack. With these tweaks, it is bug-free crack.
