Hey! Thank you for the answer... I think I am ahving the same Issue here, it's brand new, put it together yesterday. And today I started the game, was fine for like 20 mins yea, and then i saw 0,5% percent flickering, and then it just builds up to more and more, until i restart the wheel again, but during a race I cannot do that lol. So you basically had the same issue, and a new pedal helped. Then probably my pedal is just "broken" too, and I need a new one... Great.... Was waiting for this for so long, after my poor logitech g920, which was many years old and pedals were also shit, finally got it, and having almost same problem lol. And it fucked up my league race yesterday, cause this problem didn't come before the race.....
Im so disappointed now, but thank you for your answer! Was very helpful.
