@Samuele:
Nice to see progress
Just two tips:
1) Take following values for HD display:
Sector Subdivision 1: 1200
Sector Subdivision 2: 9000
You have extreme subdivision and if you are not careful the curves will look worse graphically than without HD feature:
Maybe you can also take 1000 or 800 for SS 1 - but I would not set it lower than this - or you have a lot of work to smooth everything.
2) Pay attention to sections like this:
This aspect is very important for smooth driving. Rotate sectors in way that the cc car direction (white lines) changes constantly and smoothly.
That's why the fixes for Surfers Paradise and Adelaide took so much time. For Adelaide I had to fix about 80% of all sectors, either their position or their orientation and often even both.
Here just an example for comparsion. This is a section at Oulton Park (I am going to fix in the near future).
This section is very bad and it's not possible to drive there smoothly. The cars jitter extremely.
Look at the white cc car direction lines. There is an 45° angle between them and the sector position. That's far too much. The orange lines indicate the approximate correct position and orienetation.
of course it's not extreme in you case
it already looks pretty fine. Just wanted to inform about this as it might cause serious problems at slow and tight corners
