I can tell you that it already drives waay better than any of the shift games. There's zero input lag and the FFB is already much better. The cars actually feel connected to the road. The physics are still basically a placeholder thought because they are working on a new advanced tire model and dynamic physics system.
In order to get the colors to look like that you have to change the hdr to halbic filmic, which tends to make the cars look good but makes the tracks too bright. Those are straight from gameplay though and have not been edited in any way.
