Anti Aliasing on or off?

global settings always override software settings.

I set Vertical Sync to "always on" through the nVidia control panel (I hate tearing), but I also set it to match within the game. I don't know if this is accurate, but I read somewhere that some games have problems when their video settings mismatch with driver setttings. As far as AA goes, I always set that through the game because I run different games with different settings. You can do the same thing through the nVidia control panel with the game profile options. However, I just leave AA on "application controlled" and set it within the game. But yea, driver settings overide application settings.
