It's not bad, but it has some serious instability issues and there's a few inaccuracies too.
A few times it's caused my PC to crash, whereas other tracks don't do this.
Tertre Rouge is horrendously wrong. There's no elevation change on the run up to it, the wall on the exit is far too close, and you should be able to do it almost flat-out in prototypes, yet you can't because the corner isn't right.
The rest of the track seems to be okay from what I can tell.
