remember this: http://twitter.com/repi/status/20028015661#AND THIS
"Well, it's not 2011 just yet here in North America, so I can't say this is the first bit of bad news of the new year, because it's very old news from earlier this year.
...looks like those of us using XP will need to upgrade to Windows 7 and a DX10/11 GPU if we want to play BF3.
Johan Anderson, aka repi, a Rendering Architect at DICE who is working on Frostbite and future DICE/EA games made these interesting tweets recently:
DX11 by far, it builds upon DX10 and fixes some of the weak parts of it. FB2 will take it much further
Frostbite 2 only supports the DX11 API but both DX10 and DX11 GPUs. No DX9 support at all though, time to leave legacy HW behind.
Now that I look back, this is not necessarily "news" given that in the summer he had this to say:
Frostbite 2 is primarily developed for DX11. XP & DX9 is _not_ supported, 64-bit OS is recommended. Lots of time to upgrade if you havent!"
Etc..etc..ect. ad-infinitum. You get the idea.
