However, the full version should have better driving aid settings (not this casual, racer, king stuff), or at least that's what i've heard. NFS has never pretended to be a sim, so if the physics are arcadey, it's ok, if you aren't able to do a hairpin at 200+ kmh like in carbon.
Well, it's impossible to make something worse than carbon, and, judging from the screenshots i've seen, it's gonna be the first decent NFS since Hot Pursuit 2 and the (imho excellent) Porsche 2000/Unleashed.
Dual core is only a type of processors, which have 2 cores.
The name is core 2, which then splits into duo and quad.
AMD also has Dual Cores, there even was a dual core based on pentium 4 architecture.
