Hi there, I tried to rerecord the line and make new hints & new track borders. Still the AI is not the fastest around, they especially are slow from Burnenville to Malmedy. Also the AI are totally insane in the retro F1 cars like the 312/67 and Lotus 49 and try to pass at places where it's impossible, so often it's hit & miss driving against them. You'll see them fly around quite often.
It's a lot better in the 917K for example.
