Re: Everquest 2. I think I may have a partial solution to stuttering.
Personally I blame them both, but put the most blame on NVidia, not because they are probably more at fault, but because they put TWIMTBP or whatever logo on the thing. They are still hyping the crap out of that logo, so it should actually mean something. If they are going to let a dev company put that on it's box, then they should be taking a hand in making sure it runs better on thier latest gen hardware than on the competitions 2 or 3 year old models.
That or Sony shoudl pull it and put whatever ATI's partner program logo is on the box/intro screens.
