Why do you keep asking about sim steering? If you want to know one aspect of Forza that is broken, and has been since FM4. It is Sim steering. All it does is increase the risk for reward, and by doing so makes ALL the cars not only overly twitchy. But excessively hard to counter steer. I have played an absolute ton of racing games, both with a control pad and a wheel. Arcade and sim. And not one of them feels like Forza when Sim steering is turned on. Not even the likes of iRacing and Assetto. If the people who are having issues are using sim steering, then that is one cause of their woes. Still, it is possible to drive with sim steering turned on. And I can quite easily do so. But I don't see how making the handling unrealistically difficult, serves any other purpose but for bragging rights?
Of course it will look different, the view used in my Forza video isn't the same view used in the real life video you linked too. But by you providing footage of the real car around the same track, I was able to take note of how the driver was using the steering wheel, and how it compared to the movements I made on my Logitech G920 wheel. Which, to be fair, was the only aspect of that video I was paying attention too. That one aspect alone told me everything I need to know, and that the car handles similarly in Forza to that of the real world car.
You have also taken what
@ImaRobot was saying out of context. They wasnt saying that Forza 6 and Pcars drive the same on the controller, but that you still have to use delicate precise movements to get the most out of the cars in each game.
If you want to compare to Pcars though, you will have a hard time where I am concerned. I am a WMD member and backed the creation of Pcars, and there is barely anything sim about it in terms of the cars handling. When one can drive a Caterham around Cadwell Park while drifting faster than someone not drifting, it really brings into question how "realistic" something is.
