For PIV 2.26 GHz, 768 MB DDR RAM, Radeon 9600XT DirectX9.0b and it hooks given the minimal settings when several cars driving on the screen, besides the computer opponent can go with the same horsepower numbers much faster than you in spite of equal cars, no matter what settings is carried out on the vehicle. I would not buy it again! Only costs nerves and money for a new steering wheel!
