As some other users reporting here, most of the time I have very high pings and disconnects from servers. After a disconnect it is quiete impossivel to join any other server. Ok my DSL connection is not the best (only 600 download / 160 upload), living in the south of Brazil, but with rFactor1 I still can have online races with servers in USA, Europe esp. Germany all around the clock. So, there must be something different in netcode of rFactor2, which is invoking this phenomen, I think. In order to get help I found this very interesting site with lots of tweaks for Windows7. I am using W7 64bit Ultimate. http://www.speedguide.net/articles/windows-7-vista-2008-tweaks-2574 I would like to have a list from the responsable developer of ISI, which of these parameters are mandatory/recommended for a good online racing experience with rFactor2. May be, there are other important parameters to mentioned? Thanks in advance!
