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 :)
Tell me if it works
