From the title's site -examples-:
"Assetto Corsa Competizione is the new official Blancpain GT Series videogame.
Thanks to the extraordinary quality of simulation, the game will allow you to experience the real atmosphere of the FIA GT3 homologated championship, competing against official drivers, teams, cars and circuits, reproduced in-game with the highest level of accuracy ever achieved.
Sprint, Endurance and Spa 24 Hours races will come to life with an incredible level of realism, in both single and multiplayer modes."
"Assetto Corsa Competizione is designed to faithfully recreate the performance and the driving experience of real Blancpain GT Series cars through a sophisticated mathematical model that accurately replicates tyre grip, aerodynamic impact, engine parameters, suspensions and electronics systems that determine vehicle balance, as well as the influence of mechanical damage on the car's drivability."
"Thanks to Laserscan technology, every official circuit is recreated with the utmost accuracy: all curbs and details perfectly fit their real counterparts to grant a gaming experience as faithful to reality as possible."
I am thinking that these tells the story.In fact these is nothing written in their site to suggest anything different than what I wrote.
