There has been a lot of talk saying Project CARS is complete rubbish with a controller. I've even had some people accuse me of driving with a wheel in video's I'd said I'm driving with my X360 controller. In this video I clearly, and definitively prove that Project CARS works absolutely fine with a controller and no assists. I start the video by setting up the buttons on the controller, showing I did not change any of the calibrations, and then showing that the game is set to realistic damage and driving physics.
I then take three laps around Watkins Glen GP in the E30 M3, a car with no electrical assists. After the race, I exit back out, and show you again the controller that I use, and the realism settings, to leave no shadow of a doubt that this, and other video's on my channel were clearly using the X360 controller. It's a harsh reality, but inability to drive a car in game with a controller boils down to either lack of skill, or a worn out controller. In the case of the latter, you can use deadzones to greatly improve your drive. For the former, just practice smooth application of the throttle and brakes.
