Firstly, we learn via Twitter from DICE rendering architect Johann Andersson the engine BF3 is built on -- Frostbite 2.0 -- is "primarily developed for DirectX 11"; XP and DX9 won't be supported (though you may be able to hack it). Also the engine will be especially optmized for 64-bit -- thankfully a lot of you have chosen the road less travelled. Good news in itself, but since consoles only support DX9, the implication is the PC version will be a "true" PC game.

ついにDX9を手放すかぁ。真のPC Gameの先駆けになりそうだ。もしやCrysis 2のPC版も・・・いずれにしてもPCを見捨てていないからよしとしよう。
