Is this common?

[Mr_Zooly]

First my system specs:
Win 7 64
Phenom 2 x4 @ 3.4Ghz
GTX470 1280Mb
8Gb DDR 2 RAM

Now the issue:
Framerate is stuck at 1FPS no matter what I try with detail and config and this is with DX10 option, after a while I decided to try DX9 with startling results like frames between 100 down to 20 (over built up areas) however I can't get the Nvidia control panel to change anything in game (AA etc..) any help or advice would be appreciated.
