I had the oportunity to try Project Cars on an extremely highend PC this week (I built it for someone and he wanted me to pre-install it). I'm no race simulator expert, my favourites were the first Dirt games (Dirt 3 was a major diappointment). I was a bit disappointed with the graphics on project cars, I'd expected more. Although really good racing games keep you so concentrated, that you ignore the graphic detail anyway. The real strength of project cars is the fact that you have a massive choice of cars and tracks available from day 1, without having to "jump through the hoops" of having to complete some tournament.
