The profile may be not working because of the parameters you use launching the game (see the shortcut)? Are you using nhancer?

I would get nhancer (the lastest one that supports the 169 driver series) and create a custom profile for your custom executable of bf2 (which is bf2net.exe right?) then add the Anti-Alising compatibility to the profile, remove the Dynamic tiling by changing its value to 0, set texture filtering to high quality and disable all optimizations, enable gama correction, disable Enhanced AA (it should work with it enabled too), use supersampling + whatever you want of AA (4x of multisampling is already enough).

i am not using nhancer and the parameters on the shortcuts are the same (as i edited both...)
i wonder why nvidia does not identify the games by the executable signature... instead of filename (too lazy to implement this? )

They identify the profile to use by reading the shortcut path, there are 2 methods, the executable name alone or executable name + path. You should try nHancer to create profiles with the identifier executable name alone.
