I like the way this track is done. rFactor is a sim, it is all about the driving, as realistic as possible, it is not about photorealistic looks. And this track looks very "race sim", very decent. When seriously driving, you won't see extra details, and extra details would use extra computer power which then is not available for decent physics. So when I can choose between two different versions of the same track, one which looks like this Slivin International circuit and one which looks a lot more photorealistic with a lot of detail, I would definitely go for the "race sim" looking one.
It is a pity this Slivin International circuit did not make it to the real world, it has a very nice layout, but thanks to rFactor, Bobs Track Builder and Stefan we can drive on it !!!
