JA wont run in DX11, if i recall older games and apps have to run in an emulated DX10, unless they're engine will support DX11, recently on windows 7 pro, 32-bit ive been having some older games, have some interesting graphical issues, menus work etc, but when you get into a session, the game spazzes out and the models are basicly exploded and all rendored wrong, fun times in windows 7
