Hello all, im having trouble with the newer nvidia drivers on my dell m1330. Everytime i upgrade my drivers from the factory set drivers, Windows Aero lags. When i open, close, minimize windows or use flip 3d there is lag...and the animations are all choppy; which is really annoying.

So far ive tried the latest driver from dell, the 169.09 drivers, and the 163.44 drivers. I see an increase in 3dmark scores when i make an upgrade to any of these drivers and my fps in most games are increased, but the problem is that they lag in the vista interface. Right now im running the factory drivers again and vista is running very smooth. Anyone know whats going on?
