A few questions:
1. Are you trying this in Fullscreen or Windowed Mode?
2. Are you enabling the Anti Aliasing with your graphics card's menu or is there another way you are doing it?
3. When exactly does the game crash? Is it while bursting into the area, or shortly afterward?
4. When the game crashes, is it the vista.exe / psobb.exe crash? If not, what kind of crash is it?
5. What graphics card / operating system are you using?
