It doesn't matter. Neither ATI nor nVidia are going back to a full-screen supersampling technique. This should be absolutely obvious to everybody by now. This means the ball's in the developer's court.

False. MSAA will never apply AA. SS will if the correct sampling pattern is chosen in the x2 case
You seem to misunderstand. With 2x AA enabled, there will be some edge angles to which no AA is actually applied (i.e. when the triangle edge is parallel to the sampling pattern). This is not the case with 4x AA or higher.

Exactly. Being an EE with more than 10 years of real work experience has taught me every thing about engineering is do-able so long as you are willing to pay the price. Fact its every single design has to make trade offs in order to meet the design goals, product specs or ship date. ATI's AF is not broken. Its working to a margin that is acceptable to ATI and for 99.5% of the other people out there. Sure its not perfect but ATI new what they were doing and agreed that the performance increase is worth a few cases were it falls to a level at or one degree worse then its competitors. Others may disagree and that's fine as they have other beliefs.
If you're an EE with so much experience, it should be obvious to you that this is not a performance optimization, but a transistor budget decision.
