After studying http://www.racesimcentral.net/
screenshot and the difference is huge. The addition of the following effects in the following order 1) distance blur, the further
the more blur in two layers [far,horizon] 2) noise addition, also in two layers [close (more),far (less)] which gives the tarmac a
much more realistic view and gives a true distance feel to it 3) addition of blur behind the cars, to simulate the heat and dust
These changes where only done after close examination of a dozen real examples.
