Gran Turismo 6 general Physics Discussion(as well as video)

i don't know if this was discussed or posted sometime i found today this video of gt academy final with lucas ordonez and what i saw is the nordschleife where he drives is totally different from the actual one i think looks better

 

That's the GT4 version of the Nordschleife, before the GT5 version was finished. It might look better on the small screen, but it'd look terrible if you saw the low-resolution textures up close. Plus the GT4 version obviously lacks weather and time changes.

 

in my opinion the textures of grass etc is better and not all green like is now

 

Guys. Textures do not equal physics...?

This is my first lap at the GT5 Nurburgring track. Graphics are amazing, the driving sensation is really close to real life!! Now I understand why Polyphony spent more than 5 years to create this "pearl"!!
