I have installed the subjected game on my windows 7 installed laptop and when I started the game everything works well except when the race starts the environment is black. But the car, route map, etc are visible perfectly and the car is running smoothly. I have tried to update my display driver and my pc meets all the system requirement. My graphics device is intel chipset 4 series.
I have downloaded the latest drivers from Intel's site http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Desktop+graphics+controllers&ProductProduct=Intel%C2%AE+HD+Graphics&ProdId=3231&LineId=1100&FamilyId=39
and the problems were gone! Now the game runs on max settings (though a little bit slow)!
So, my advice to you:
1) Download the latest drivers for your integrated Intel video card (the drivers on Intel site are as of October 23, 2010)
2) Turn off "blur effect" in NFS graphic options
3) Set other graphic settings by "trial and error" to get the game running fast
4) Enjoy it :)
