As the name suggests it is indeed converted from FM7. It's the one I keep installed. Imo it is the best available one for AC.
It is the best, but it's not perfect sadly. As suggested, there are a lot off small differences to other laser scanned tracks and real life, and the problem is, these are all in places that are very crucial for "surviving" the lap around that track, which is a challenge even without these. For example here are 3 big differences (that may not look as much, but are very important), that make driving a lap around the track much, much harder than it already is:
1. the "additional" hump at the top of the mountain before the Sulman corner, makes you loose traction with the road because of compression and it is to easy to hit the wall if you are not on ideal line, which in traffic you never are. The AI also almost stops here because of that instead of taking it almost full throttle like IRL
2. The Forrest elbow outer brick wall is to close to the track and has an overexposed "kink" in the wall right at the exit of the corner, which makes you crash into it if you go just a few centimeters to wide. And effectively this ends your lap or even race. Also forcing you and AI to go much slower and efectivelly taking away one of few overtaking places.
3. The off camber before the second corner in the chicane in The Chase is to extreme, which makes you spin if you are not on an ideal line. Which you are not, if you are in traffic. And that makes you loose another, probably the best overtaking place on the entire track.
I know this looks like really small niggling points, but they really are not. It changes the immersion completely. The track is difficult as hell to go through as is, and these three discrepancies make it almost impossible to drive on a limit in a competitive race. If you are alone on the track, this is not so crucial, as you are able to stay on an ideal line.
