Ok, with today, I've finished to use every track/layout of the game. Missing only Drags and Drift (which aren't real tracks) and the Hillclimb Trento-Bondone, which I need more test to learn it before any real attempt.
Here the most interesting of the 3 videos I uploaded today. Ferrari F40 at Imola, using Street 90s tyre compound, 8am time for a nice sun visual with 95% grip.
Note that to increase FPS for online races I disabled Post-Processing filters, which also caused a non-realistic glare. That glare is shown (so realistic) on videos just because the glass of the cameras give that effect, but is not directly seen by the driver (so non-realistic in a driver-visual purpose). Although it is still not enough shiny and blinding, probably somehow a middle-way would be the most realistic option.
