Visually, this is a very pretty track. What I am less satisfied by is the physics mesh to drive on - particularly in the hairpins, it seems very rough, leading cars like the DTM-190E (Kunos) to literally bounce their way through them. This impairs the driving experience.
I recognize that the real track is not exactly smooth, but some of the bumps encountered while driving here do not make sense. Once this is fixed, I will happily rate this track with 5 stars.
