I loaded it up and started playing. There's definitely something wrong. It's running in S..L..O..W....M..O..T..I..O..N..!
The speedometer says 75mph, the car acts and looks like 15mph. Otherwise the graphics are very nice and with 5000 square miles of area to explore, it should be fun - if they can fix it.
For now it's back to Burnout Paradise. Hope to run into you there!
