Assuming that there is a problem with 9800 series Radeons or ATI cards in general:
There need to be a fix for ATI cards. The game's running extremely slow on my system, and it's definitely exceeding the requirements. I'd love to play the game demo more in-depth, but I can't until I can get the game to run smoothly.
On another note, the voices do need a little work. The voices for DD were great in general so I was a little surprised to find the weaker acting in some parts of the demo. However, this is more of a minor quibble than anything.
However, from what I can see, the game looks really really good and it seems like it'll be a worthy successor to DD.
