Crysis will probably be playable on Windows Vista with a DX9.0c compliant videocard ; of course, the DX10 specific graphical feats won\'t be present.
I guess it\'ll be kind of like playing HL2 with a DX8 card.
So, i expect ; speedy dual core cpu + Vista + DX10 videocard + 1 - 2 Gb ram.
I wonder what Ati\'s unified shader architecture will do for DX10....
