@doctordonkey: Wait, the press release specifically says the content update to 1.10 is free across all platforms. Wouldn't that include all the graphical improvements?
From what I understood, there is going to be another version of the game on Steam. Like totally separate. The old one will be DS2 DX9 and the new one will be DS2 DX11.
This means that all of the improvement that aren't related to the game engine will be implemented to the old version, while everything else will be exclusive to the new separate release.
