For years, I've been waiting for a PC driving game that combines realistic driving mechanics with cutting-edge graphics. Project CARS appears to be that game. Just look at the latest trailer:
Stunning visuals? Check. The driving mechanics are solid, too. I bought into the crowd-funded title a while ago, and I've spent a little time playing the latest betas with both an Xbox 360 controller and a fancy Fanatec wheel setup. Both feel excellent. There are plenty of configurable driving aids to suit different skill levels, too.
The betas are still a little rough around the edges, but Project CARS isn't due for final release until November. It's coming to the PC on both Windows and Steam OS.
