I really want to like this game, but I am getting somewhat poor performance considering my hardware (it runs Oblivion well, so this game has no excuse). Of course, the fact that Intel and ATI logos show up on startup when I'm running AMD and NVidia may be that problem :).
I did install the Physx driver (yes, that is really weird). Other than that the game looks like a lot of fun, I just wish I could get the framerate up to acceptable (at least 25-30) levels.
