Well I use these drivers with my 8400M GS (acer 7720g notebook) and they are just the same.
Same sheet, different day...
I wonder what "Added support for the following new GPUs: * GeForce 8400 GS" means.
At least we finally know that the 8400m gs was not supported before
Compiz is still laggy to death and firefox tab switching and scrolling is still lame.
Shame on you Nvidia
