My car disappears for other players while online. I have no indication that anything is happening. I see the other cars, there pings don't change, there is absolutely nothing on my end to indicate that others can't see me. I'm running win 10, and I have a solid connection.
What is your network speed set to, in the game. This used to be an issue, but I'm not sure if it is anymore. Also, if you press ctrl+c while driving, does the purple bar go all the way to the right?
My internet speed is 100M, I have the in game network setting at 75M Down, 70M up. The purple bar stays around 40%
