Voice of reason required again. I use an Nvidia card (as do 3 or 4 other of the 5 regular guys I play BF4 with). It isn't going to be a game changer for me or them, is it? Am I going to abandon my gfx card (which is plenty fast for me now) to join AMD? No, of course not (though I am still waiting on a R290X Lightning to surface ). There is no doubt whatsoever Mantle will be excellent for the owners of GCN cards but because of it's specificity - it cannot be a game changer unless the majority co-opt into it. It doesn't matter the performance increase it brings because it is not going to bring it to the majority of gamers. Again it's another 'buy in' development. For this special super dooper thing to work - you need to own a GCN card. It's tha same reason G-Sync will be doomed to be niche - it requires extra investment AND potentially a gfx card purchase. How many 290(X) owners will buy a G-sync monitor and a new Kepler gfx card? Probably less than the small amount that will swap to AMD from Nvidia for Mantle. I like the idea of Mantle but it cannot be implemented to be a game changing development in a market that is so very fractured. Mantle absolutely requires more than AMD for it to work. As long as Microsoft want to maintain DX11.x and Nvidia have such a large share of discrete cards, Mantle won't be a game changer. It is not ignorant (nor worse, to be a Hater) to say what I am saying. I AM saying Mantle should be superb for the games it is coded with and the cards that can play it but you really need to appreciate the market clout Microsoft and Nvidia have in the industry. If Mantle proves a threat, rest assured Nvidia will do something about it (they are after all vicious corporate bastards ). FTR, I think AMD and Nvidia should talk about it at the coding level. I think as folk have suggested, once it is matured it should be handed over to the Khronos(?) group to oversee in an open, non proprietary way. I just don't see a company like Nvidia (that everyone loves to hate on a business level) will let Mantle roll over their perceived superior 'performance' in GPU's. All Nvidia have to do is make more investment in AAA games (AC3 & 4 and Starcraft(?), I think are good examples) which cripple AMD hardware. Mantle is good, yes, no doubts, very good for GCN. But it does not have a very straight forward or easy future. It can only truly be a game changer if Nvidia (and Microsoft) let it. To be fair, it is in AMD's favour to approach Nvidia and propose something to make it work out. If Nvidia are given enough tech knowledge to work with Mantle then they can help out with the development costs for Mantle coding in games. I read that it costs an extra 10% to code for it in development? That's a lot for AMD to spend on more and more games. If Nvidia were co-opted into it, they could then share that 'sponsorship' cost in games. That way Nvidia get the tools for free and pay for the game development directly and AMD reduce Mantle coding costs on their side. Very naive but so is much of the Mantle discussion.
