I'm currently backing up all of my major important files on DVDs and an External Hard Drive and I am planning on installing a clean version of Windows Vista Ultimate soon. I do know and am well aware that the Vista operating system is extremely buggy at best and there are several known issues with it. But I want to keep up with technology and I want to leave Windows XP Professional. Now, I'm wondering what types of issues will I expect with NS upon installing Vista? I believe my computer is Vista ready. I have all of the latest drivers and legacy devices installed. Here is my current setup:

Windows XP Professional Service Pack 2
Intel Pentium 4 Socket 478 3.4 GHz
XFX 7600GT 256MB AGP
Sound Blaster Audigy SE

Latest Drivers Are Installed

I'm running:

Vista Ultimate
Intel Q6600
GTS8800
On board sound(Will change this soon because I have trouble hearing where footsteps are coming from.)

The only problem I've had in NS(other than crappy directional sound) is that it doesn't close properly. The game runs fine but when I click exit Vista says the program has stopped responding(duh). It doesn't crash or have any other problems, just the message comes up for me.
