idk, I had the freezing happen a couple times...so I deleted a guy from my autolog who had records and then it stopped. I think Autolog causes most of the freezes.
I mean when I first got the game I never had anyone to autolog and never had freezes...then I had one guy, everytime I open autolog the game freezes...fixed it by added another person. Then for the first time I got the freeze on nurburgring and then a couple other tracks...deleted the first guy who had tons of autolog records and gone.
anyways, I only get weaving with certain loaner cars.
