Em... This is clearly a marketing hype. Melting dosent mean it will look better, it just means will not be optimized for PCs, so no matter what CPU/GPU you ahve, they will run at 100%, and still have crappy frames (like deus ex 3 had in some areas and with some animations).
Besides, they did promise DX11 at release on PC version of crysis 2, and then they simply didnt. Why would i trust anything they say? (Not to mention they didnt add DX11 Native to crysis 2 with the ULTRA quality update, they only added dx11 support for specific elements of the game.
I do not think there has been a fully native DX11 game on the market yet, and the closest thing to it maybe matro 2033? Hard to say, but PC gaming has sucked for some time now, meaning few games are actually really AWSOME, most are shitty, and there are a few good'ish.
I guess ill do same way ive been doing alst 2 years: Watch on youtube the game for a while, then decide if its worth the money or even then time.
