Hey, I am testing my graphical settings because I always have problems with stuttering the car. Now I was busy at Silverstone, even at the very lowest settings he kept stuttering now and then, with high peaks in CPU usage. Then I tried on Indy F1 layout and my settings could immediately go up again. Is this on my PC or is this really the circuit itself. My PC specs: AMD FX8120 AMD Radeon R9 200/ HD 7900 Windows 10 I'm sorry for my bad English
