Who said anything about need? If Nvidia came on the scene and said "hey guys let's get AA up and running", there's no reason for them to accomodate ATi hardware other than some misguided sense of fairness. Like I said before, ATi users don't lose anything by Nvidia gaining AA.No, Trinibwoy, no. Don't play with words. You doesn't need to "enable it" for every platform, one by one. You know perfectly that standard code written over an standard API, don't need any kind of specific instructions to be enabled for each platform/HW piece.
