I leave you a video of GT5 where I've mixed the onboard of Autobacs with the repetition and I've applied a filter to have a more realistic color and lighting and the helmet cam effect.
Coinciding with the most famous endurance race in the world and celebrating its 90th birthday, I upload this gameplay of Gran Turismo 5 (dual view) give a lap in this historic circuit with the Peugeot 908 HDi FAP - Team Oreca.
Final comparison between Gran Turismo 5 and Project CARS (pre-Alpha) in the king of the circuits, the "Green Hell", Nürburgring Nordschleife. The comparison is both from the cockpit of the Ford GT40 Mk IV.
